Not a scam but very poor business practices. There are wonderful sellers and great deals to be had if nothing goes wrong but they will charger you for items not received. I was shipped wrong item, men's boots for $30 and I paid $65 for my order, but didnt receive my order. Postmark hasnt responded to me and in fact charged my account without my accepting the order because I never received my order, but someone else's for half the value of mine. Luckily the poor seller who hasn't had a response from poshmark either, has been wonderful and we are working out the problem ourselves. They will find themselves in court if they dont improve th heur practice.

Because its not a scam, youre just too stupid to read the rules and instructions
