If we ask you for a cashier's check, do not send us a check claiming to be drawn from a business in Raleigh, NC when you're FedExing it from a Kroger's pharmacy in Kentucky. Also, do not print it on your inkjet printer. And, make sure you use a decent resizing algorithm when you enlarge that scanned signature. We are not that dumb. Neither was the bank manager I showed the check to.

Craigslist vs ebay.

Cause I got a lot of camera stuff I need to get rid of.
There are, apparently tons of common scams out there. Google.
The one we just met was: I want to buy your furniture. I will send you a cashiers check for enough for the goods plus enough to pay my mover. When the mover shows up, pay him. Of course the cashiers check is fake and the “mover” is in on the scam.
Our guy was silly enough to send a obviously bogus check. We’d never heard if that scam before.
