The credit can be used on future video game purchases and usually appears within 3-5 days after the release date. There is an expiration date on the credit.
Metal Gear Solid 4 is listed as 27.99 but all the actual prices are above it. The email notification will not start because the price I am willing to pay is more than the fictitious listed price.
I had to really twist the associates arm to get the price check and then the guy got upset because he didn't get the list. I picked up some extra Metroid Prime copies. I can ship them out for 13.00 bucks a piece. PM me if you are interested.
