I dont remeber the day I purchased the scanner Dec 2011 as far as exact day I wish I new. And it seamed the associate that sold me the scanner is no longer working there.They do have a record of the purchase. That record show's that a unknown name customer purchased specific catalog number item on certain day at a certain time in a certain store for CASH. Unless you purchased the extended warranty, there is no record of your name on the sale. Since you did not purchase the item with a credit or debit card, there is no way to link you, as an individual to the purchase.
If you can give them the day and the sales associate remembers the purchase, they might be able to link you to the purchase.
This is true as far as I know as well.As I understand it, GRE will not work on radios made for Radio Shack.
That is a little bit overkill. Any store can look up a credit card/debit card transaction.
