I'm gonna start working electronics at my store and my trainer told me that selling ESPs is very important. I understand why since they make a lot of profit. Anyway, my question is simple: how do I ring one up? I know I have to scan the appropriate price range. When it asks to scan the serial number, do I scan the product or the barcode on the bottom of the esp itself? For the gaming plan, do all 5 games have to be purchased the day of the console purchase or can they come in later and buy a few more games and still be covered? Thanks for the help!
