The advanrage of Cafepress and the like is that they only make prints (or anything else) when the customer orders one. But that does push up their price. You're paying them to do more than just make the print, as well. If you get the prints pre-made, and keep your own stock, do your own selling and dispatch, you've got to figure in those costs. Crude example: Pay CoffeePass $20 per print and sell at $25, you get $5 per print, with no physical prints unsold, and simple tax accounting. Go to the local Canker's, pay $10 per print for 20 prints, and sell at $25. You've got to sell 8 prints just to cover the printing cost, and you're still $40 behind. And there's extra admin costs. You may end up with more money, but you're risking more to get it.
