It's about who is taking the risk, with BigCartel you shell out money upfront to buy shirts + print (guessing how many to get in each size, how big an order you need, etc.) then try to sell them. TeeSpring is kind of like a Kickstarter, you setup a picture of what the T-shirt would look like when printed and then no money changes hands until you hit your "funding level" of a certain number of shirts, and there's no excess inventory because they only print exactly the right number for the sizes that people ordered. It's a really interesting model.
