What I Learned Doing 42 Comic Cons in 2025 (part two): Costs & Cashflow

I’m Mark Stay, author of the Witches of Woodville series and The End of Magic trilogy and welcome to the second episode where I’m sharing what I’ve learned from doing 42 comic cons in 2025…



Let’s talk about costs, sales targets and cashflow. Ooh, exciting! This episode all stems from one very long question from…

ZOË RICHARDS, author of Tell it to the Bees and Garden of her Heart (not an author of fantasy or science fiction, but she sells at craft markets)

Zoë asks: What do you class as a good day/event?

I’m Mark Stay, author of the Witches of Woodville series and The End of Magic trilogy and welcome to the second episode where I’m sharing what I’ve learned from doing 42 comic cons in 2025…

Let’s talk about costs, sales targets and cashflow. Ooh, exciting! This episode all stems from one very long question from…

ZOË RICHARDS, author of Tell it to the Bees and Garden of her Heart (not an author of fantasy or science fiction, but she sells at craft markets)

Zoë asks: What do you class as a good day/event?

I’m not after sales figures, rather the formula you use. This is what I’m using, and I’d love to know if it aligns with yours.

Zoë lists her costs as…

• cost of stall

• additional costs (travel, parking, refreshments)

• depreciation costs (banner, bookmarks, table cloth, display materials)

• Costs for debit card sales (each sale incurs a small fee)

• cost of books ordered (like me, she gets author copies from her publisher at 50% RRP)

Then Zoë tallies that against her:

• targeted sales

• actual sales

• income from sales 

And the final result is:

• Total income from sales

• Minus total costs

Zoë continues: Is this the right approach? I find myself wondering if I’m doing well or wasting my time. I don’t have opportunities for comic con events as I write the wrong kind of books so mine are craft markets, which don’t always attract readers. 

Thanks Zoë and that’s pretty much the approach that I take: I tot up my costs, then estimate how many books I need to sell to cover those costs and target myself accordingly. You can tell I was a sales rep, can’t you?

I keep a spreadsheet with how much the table costs me and the estimated petrol expenses (I use the RAC calculator).

So I can tell you now that in 2025, I sold 1974 books, with a turnover of just over £20k, spent nearly £2.5 on petrol, and nearly £3k booking the events.

What I don’t track are those depreciative costs: the banners, the tablecloths, the bookmarks (and I’ll talk more about them when I do a tour of my table in the next episode)…

And I don’t track my biggest expense: stock (£6.4k in 2025),… because it’s the expense that never stops and presents its own issue: cashflow.

Now if you’re just starting out, and only have one or two books to sell, go and fetch the smallest of your violins because this is where I complain about the expense of having to regularly stock up on 9-10 published books. It ain’t cheap… 

Like Zoë, I get my Witches of Woodville books from my publisher, Simon & Schuster, at a 50% discount. And I get my self-published books from Bookvault and they cost between £5-6 per copy.

What am I complaining about? That sounds like a good markup… Well, I’ve realised that in order to have the stock arrive in time, I have to place the stock order two weeks ahead of the event. 

So if I’m coming off the back of two smaller, quiet events and then have to order for one of the bigger comic cons, and if I’m doing this every weekend, then I’m often out of pocket. Big time.

Yes, there’s a good chance that I’ll make my money back in a couple of weeks at the bigger event, but it means that I often end up overdrawn and it gets a bit squeaky bum time… and that’s why I’m not doing this for the money. Because, by the time you’ve totted up your expenses (I’m also paying for editors and artists and other expenses through my company, including two salaries) and paid your taxes and your VAT bill every quarter, there sort of isn’t any left.

What I get instead are readers. 1974 books that I personally signed and handed directly to readers. That’s a much stronger connection than selling something on Kindle for 99p to someone in Buttmunch, Indiana… That’s what I keep telling myself anyway. And no offence to the good people of Buttmunch. Go, Buttmunchers!

But hey, in 2026 the plan is to sell even more books! I’ve got a 5 book series, and now a completed trilogy, and more books on the way. So in the next episode, we’re going to talk about sales, and how to sell, and the tools for selling. I’ll even take you on a tour of my table. Ooh! Exciting, eh?

What I Learned Doing 42 Comic Cons in 2025 (part one)

I’m Mark Stay, author of the Witches of Woodville series and The End of Magic trilogy and I’ve been selling my books at comic cons for ten years.

But in 2025, I really went for it: selling at 42 comic cons in the UK. And I’m not alone: I’ve made lots of new author friends this year at the cons, and I know that many more are thinking about it, so I thought I’d put together a series of short videos passing on what I’ve learned…

In this series of 4 videos, I’m going to cover…

The different kinds of comic cons in the UK and which ones might be right for you.

What kit you need to invest in, and I’ll take you on a tour of my table and how I lay it out.

Ordering stock, cashflow (or lack of it) and other expenses.

And I’ll be answering specific questions that some of you good people have sent me…

Let’s start with why I do them, and the different kinds of comic cons I went to this year…

But in 2025, I really went for it: selling at 42 comic cons in the UK. And I’m not alone: I’ve made lots of new author friends this year at the cons, and I know that many more are thinking about it, so I thought I’d put together a series of short videos passing on what I’ve learned…

In this series of 4 videos, I’m going to cover…

  • The different kinds of comic cons in the UK and which ones might be right for you.
  • What kit you need to invest in, and I’ll take you on a tour of my table and how I lay it out.
  • Ordering stock, cashflow (or lack of it) and other expenses.
  • And I’ll be answering specific questions that some of you good people have sent me…

And let’s begin with the big one: 

JAN CARR

Why? What’s your motivation?

Why do a comic con? It’s a lot of hassle. You have to buy stock, set up a stall, get all the bits and bobs (more on that later), get up at the crack of dawn (or before dawn in the winter) and drive for hours to some draughty gym hall in a leisure centre.

It’s not glamorous, and I’m not doing it for the money, I can tell you that. I always make a profit on the day, but the margins are slim and the cash flow is a nightmare (more on that later, too). So the first question to ask yourself is: what are your goals for selling at comic cons? Why do them at all? Why not stick with online advertising and social media?

Online ads with the likes of Amazon and Facebook never worked for me (despite ploughing a lot of money into them over the years), and I’ve never been great on social media, but… I was once a bookseller and a publisher sales rep. I know how to hand-sell a book, and my books – especially the Witches of Woodville series – are classic hand-sell books. The first one was published in the second lockdown, so never got that bookshop boost that it needed, and when the fifth and final one was published last year, it became clear to me that my publisher had moved on to promoting other things (which happens), and that meant it would be down to me to keep the momentum going. So I went back to what I know best: bookselling.

For me, going to comic cons isn’t necessarily about the sales on the day, it’s more about creating new readers who will come back for more. A long term investment of your time and money into something that might pay off further down the line. Will it work? One of the great pleasures of doing so many events this year is seeing those readers come back and tell me how much they’ve enjoyed the books and have told their friends and have come back for more. So, it seems to be working.

Let’s start with the fundamentals: how much do these things cost…?

COSTS & CONVENTION VARIATIONS…

KATHERINE FRANKLIN

I’ve heard tables at comic cons are expensive – was it ever tricky to make back the pitch fee?

ANDREW GUILE

What does it cost?(!)

JULIAN BARR

Are big cons necessarily better than small ones?

JENNIFER TAYLOR-GRAY

Which cons were the best for you and why? Was it due to anything you did differently those days, or the con set up itself? 

All great questions. Let’s start by looking at the different kinds of conventions in the UK.

This year, I’ve been to cons organised by Bolt, Striking, Creed, Showmasters, Reedpop and Monopoly Events, plus a whole bunch of independent and local events. Each offer different opportunities and have varying costs…

(If you click on the images, you’ll be taken through to their pages for exhibitors)

BOLT/STRIKING



Both quite similar and I believe they were once the same company but bifurcated at some point. They’re really well run, the organisers are lovely (they bring round bottles of water and snacks to your stall!) and the events are aimed at families. Young families. These are more like toy fairs or collector events than comic cons (there’s a lot of Pokemon for sale) and very often I’m the only author with a table.

Table costs vary depending on the size/location of the venue and range from £65-£125 for a table (most are at the lower end of that). You pay a small deposit beforehand to secure a table, and settle up on the day. The atmosphere at these events is warm and welcoming, they have great accessibility policies, meaning they allow early entry for folks with disabilities and hidden disabilities. I really like them, though the young family demographic means that I do okay at these events. My books are aimed more at adults. I know that some of my author friends who have kids’ books do better than me, so bear that in mind. I’ve always made a profit, though.

Every now and then they have guests for photo opps and signings, but not often. I’ve done more of these events than any other this year, and have already booked more for 2026.

CREED/SHOWMASTERS



Again, these share some organisational/crossover DNA. These are generally bigger events and, crucially – for me – have lots of great guests. I’ve discovered that if there’s a cast member from Doctor Who or Red Dwarf present, then I will have a pretty good day. Fans of those shows are literate, have money and are willing to read new authors: gawd bless ‘em!

Showmasters also run the London Film and Comic Con, which in the autumn co-hosts with YALC… and that’s a huge event for SF&F authors. The readers bring their own little wheeled trolleys which they cram with books, and we love them for it.

Creed/Showmaster tables cost between £40-£100 depending on the venue and, for me, are great value. YALC tables cost more, but from talking to author friends who paid the extra it sounds like they’re worth it.

REEDPOP/MCM



I’ve been doing the MCM Comic Con in London for ten years. They were my first cons and they’re still the biggies. I think the last one had 130k people at the Excel Centre over the three day weekend. Creator/author tables cost £255 (cheaper for the MCM in Birmingham, I think) and they have a Writers’ Block, where all the indie authors are gathered in their own section. When I first started, there was nothing like this: just me and Kit Cox stuck in a corner nattering to ourselves (Kit kindly let me share his table, which you’d never get away with now). The MCM comic cons are now a very big deal for authors and because of that, they have a selection process. Not everyone gets a table and you have to pitch yourself to them. I can’t speak to why some authors get in and others don’t. I always offer to moderate panels, which has helped. And I think it helps if you’re planning to launch your book at the con: they love an exclusive.

MONOPOLY



I only did one Monopoly event last year – For the Love of Fantasy – and the Saturday was my biggest single day of the year. Bigger than the MCM… and if I’d had enough stock, I don’t doubt that the weekend would have been my biggest of the year. It’s at the Excel Centre (just one hall) but they had celebrity guests from Supernatural and Lord of the Rings. They run events in places like Liverpool, Manchester, Birmingham: I’ve not been to these, but I’ve heard good things.

DARIUS TWYMAN

What was your favourite con this year and why was it the Canterbury Gaming Convention? 😉

Thanks, Darius. It was definitely in my top 40!



Actually, the Canterbury Gaming Convention was great fun. Not a comic con, but there were a few authors there and we had a good day and I’d definitely like to come back in 2026.

I’ve done plenty of independent conventions and events, and these can be hit and miss, but the costs are often much lower than the big cons, so are worth a punt. I’ve especially loved anything with the steampunk community: like Doctor Who and Red Dwarf fans, the steampunkers are literate and lovely. The Fort Amherst event every Easter has become a highlight for me, despite being stuck in a cave for two days.

So that covers the different kinds of conventions and the basic table cost. In the next episode, I’ll be digging deeper into expenses, targets and cashflow… no, really, it’ll be fun, I promise. Well, informative at the very least…

My Last Few Comic Cons for 2025…

I’ve updated my events page with the remaining comic cons that I’ll be selling and signing m’books at in 2025. They include Croydon, Southampton, Watford, Newmarket, Hatfield, Reading, Tonbridge and the two biggies in London: the MCM and LFCC.

A couple of things to bear in mind: some of these locations are a bit like Ryanair destinations, eg: the Croydon one is actually in Carlshalton, and the Southampton one is in Eastleigh. And I’m posting this on the day that half the internet has collapsed thanks to Amazon’s monopoly of the world’s servers, so some of the Evenbrite links might need a few tries to make them work. Or, y’know, read a book instead and come back tomorrow, maybe?

Anyhoo, if you fancy a fun day out and the delightful prospect of meeting me in person (I promise to shower and shave and brush my hair) then click on the button below to find out more…

I Won’t be Going to the Midlands Comic Con this Weekend

Sadly, I won’t be able to go to the Midlands comic con at the NEC centre this weekend, 12-13 July 2025. I ordered stock for the event at the end of June, but HarperCollins recently moved to a new distribution centre and it’s had ‘teething problems’, which in my case means I’m still waiting on stock! And without stock to sell, there’s not much point in me going, sadly…

However, I will be at the Guildford comic con on 19th July, and the Maidstone Museum Steampunk day on 26th July. There are more details on my diary page here.
