(!) completely forgot about that theme

I wanted to ask you about online shops.
Well.. I have different stuff: about 6 packs of stickers, same amount of postcards, + posters, sketchbooks, lil books are also coming soon. I just.. have no idea where to show and sell it.

I faced with tictail and storveny (hope i'm right), redbubble.
But i know nothing about them.
Ok, i guess i can just seriously read their rules etc....... But.

Maybe you can tell me smth about it? Maybe you have one? Or just prefer certain site?
Which is easier for you or mb you have an experience?

Thank you for attention ❤
