Like tshirts or stickers? Do you have already made them? Or just for active members?
They do exist…
… I’d recommend Sticker Mule who allow people to buy individual stickers that people have previously printed. They’re used by a lot of open source projects. I think you can also directly upload design files without even printing up large orders.
If you are active here on Meta PM me and I will make it happen for you!
Sounds good man!
