Getting ripped off by a fellow member

Um....

New parts can have cracks too.....

Seems like refund Less shipping is the internet standard. You buy from an individual, you run this risk. Throwing someone's reputation on the line if the refund less shipping offer is made is a bit extreme. Exactly how much time went by from, Houston we have a problem, to, No response or a get lost?

I must admit, I listed a part recently, didn't do my homework, and could've sold it in error. That's a mistake and expense for everybody involved. Honest seller and honest buyer both lose a little, no matter what, when that happens. But trashing someone just cements hard feelings and recovers nothing. If it's fraudulent by intent, that's one thing. If it's a mistake that's another.
That seller has been here long enough, I'd call it a mistake, issue an apology, and try to minimize losses for both.

OP, it sucks. It really does. But are you POSITIVE he's TRYING to rip you off? New parts can be bad, too, and people miss those issues until..... someone finds them. There can be a lot of people missing the same issue. Including you when you looked at the pics, so regardless, you made the same mistake the seller is claiming.
