BEWARE; scam artist fellow poshers.

I was almost scammed recently by an apparent buyer. I told them I had additional pictures I could email them because poshmark only allows a certain amount of pictures. They wanted to buy and offered an additional 100 for the extras I was including. Not trying to be skeptical I accepted their offer. They did email a legit check but I checking with bank and law enforcement it was a scam. They said their accountant mistakenly cut too large of a check and I was to send difference back in cash.
