From what I understand, on Teespring, you have to set a "goal" of a number of shirts before any are sold. So, if your goal is 10 then before anybody gets sold a shirt there has to be at least 10 buyers. Correct?
Seems to me that's leaving money on the table if, for instance, you only get 9 buyers interested in a particular shirt.
If I'm a buyer and go to buy a novelty shirt on impulse I'm not sure I want to wait for 9 more people. I want my shirt now.
It looks like Spreadshirt and CafePress don't have this restriction so I'm wondering if I'm missing something here?
