I thought this one was funny, until I got it 7 times today.
This scam is unlikely to hurt any pet sitters, but it's funny. Basically these barely-english-speaking scammers scour websites for stuff people are selling. Then they just fill the item and email address into a form letter, offering to buy the item in bulk for inflated prices. I don't really know the rest of the scam - probably they overpay and have you send back the extra or something.
