Is This A Scam Or Is It Trustworthy?

Absolute scam, most commonly they overpay with a bad check asking you to return a portion to them or a "shipping service" they often don't actually care about the item for sale.

There's a site that guides you on how to waste the scam artists time, leaving them less time to do real harm. There was an investigation TV show that got a scammer to fly to a different country with the promise of a payoff.

The Nigerian pop song "I go chop your dollar" celebrating such scams.
