Are you printing & shipping them yourself? I considered selling stickers at one point but print costs under 500 was too high, plus the hourly requirements of doing my own pick& pack. I thought about hiring the neighbor kid, but casual hiring seems to get messy/illegal fast.
Yep, print and ship myself. The shipping can definitely be expensive for a single sticker depending on where it is being sent to but I charge anywhere from $15 to $25 per sticker (all original art and I think that’s why I can get away with the higher prices) so shipping doesn’t dent into that too much to not make it worth it.
There are many services that do the printing/shipping for you, they take a big cut on the price though but you don't have to worry about anything at all.
