I think it's pretty easy to get drop shipping done automatically they'll even ship the shirt to the logo company that puts it on and then ship it overseas from there. Best bets to go through alibaba or aliexpress perhaps...? Takes a little while longer doing it that way though over holding your own stock.

I'll probably buy one I enjoy crypto gear/swag/stickers for the ones I'm interested/involved with. Doge's logo probably being my favourite lol, but I'm wondering does zazzle take crypto's?
