spreadshirt prices items based on your region and then decides what to give the seller themselves, it's all automated. So I can't really give you an answer but you can look at stickers on their website to get an idea on the average price.

Problem with that method is it's unreliable. We don't know how much we'd make on each sale (even if they're just to support the website and spread some goodies I don't want to make just 1 dollar on a 20 dollar sale).

Another way would be aliexpress sellers but we'd have to set up some sort of dropshipping platform to automate as much of it as possible, plus we'd be handling customer data. And as far as stickers go on ali, they sell them by the hundred, which I doubt most people would need -- 10-20 is more realistic if we can find that somewhere.
