Hi, new poster seller on Amazon and I have some question…

Hi, I just opened a professional seller account on Amazon. I can print 80% of my variants, and the remaining 20%, with local printers.

I am in the process of authorizing a poster with Amazon. I want to prepare prints and post myself. Is it a good idea? I know many do business with PODs, but I’m hesitant … lots of negative comments.

Anyway, could someone give me some advice?

thank you!
