There are places in town where $30 will get you a valid Social Security number.
Guaranteed not ones that will get a check worth more than $30 sent to your address every month.

"There are places in town where $30 will get you a valid Social Security number."
I would question your use of the term "valid". If an illegal uses an SSN that he paid $30 for, I would not consider that "valid".
More to the point, however, is that the reason that SSNs will be required for the the rebate is that it will facilitate automated checking for dupes. If the same SSN is being claimed on multiple rebate requests, that is something that would be relatively easy to catch. I would assume by "valid" you mean that it is a real SSN assigned to some legal US citizen. Therefore, the only way this would work would be if the real US citizen did not claim his rebate.
