Internet fraud? please help if you can?

They sent them through the mail, so this is mail fraud and is a federal offense. (Besides the obvious theft). I agree, contact the authorities and report it. As for a site to check to see if they are real, there really isnt one, you can call (1) 800 221 7282 to check the serial numbers, but the ones you recieved may have been stolen and not reported yet.
