Perhaps that is the pricing for alumni? Unfortunately for first time exhibitors the prices are significantly higher.
Agreed.
Business cards are the least expensive option, at around $.07/each for front and back printing. Unfortunately they are too small to be very eye catching.
Fliers go up in price. For one convention we ran off 5.5x8.5 fliers that were fairly popular. One sided printing is around $.13, two sided $.26.
Both of these options work great for a single creator. But if there are 10 creators all doing individual fliers, that's $1.30 to $2.60 in fliers. You can combine them all into a sampler comic with twice the amount of "real estate" for significantly less.
Though we currently don't have enough interest to launch a sampler comic so it may end up being fliers as you point out.
Everything is in flux right now. Admittedly it's a year away, so a lot can change.
