Thanks for the suggestions, keep em comin.
F.A.Q.
Q1) What is this Editor's choice promotion?
A1) Any purchase of a game from the Digital Games section on Amazon.com between Nov. 16 and Dec. 31, 2012 (or the purchase of the Protoype pack in November) earns you a $5 credit to be used on the purchase of a game from the 2012 Editor's Choice Games.
Q2) Where is the code for the promotion?
A2) There is no code - the credit is linked to the account that purchased the qualifying game and automatically applied at checkout.
Q3) I didn't get the credit. What should I do?
A3) You can PM the order number that you think should qualify to Tony, or contact Amazon Customer Service directly.
Q4) Is there anything I can buy to get the credit now?
A4) No, the promotion is over.
Q5) Where can I find the eligible games?
A5) Here
Q6) I don't like the list/have all the games/ don't like the prices.
A6) There is no way to predict what will be on the list, but there will be changes between now and when the promotion ends on January 31, 2013.
Q7) How do I know how many credits I have?
A7) There is no easy way to tell. You can search your inbox for emails (Search for '1000728511' in your inbox for $5 credit emails) or contact Amazon customer service. Ignore the amount under game credits you can find on the Amazon site - it includes credits for a lot of other promotions.
Q8) What happens if Steam/Gamefly/Impulse(Gamestop) has a lower price?
A8) These price matches are handled on a case by case basis. There is a link on every Amazon product page "Tell us about a lower price" that you can use to submit a request. There is no guarantee this will cause a price match, but it can't hurt. Amazon does not match flash/community choice deals. Amazon generally does not match deals that require a limited use coupon or code.
Q9) Will Amazon price match Gamersgate/Getgamesgo/Greenmangaming?
A9) Amazon does not pricematch international sellers.
Q10) Will Amazon pricematch Origin for EA games?
A10) Amazon generally does not match publisher sales.
Q11) What time do prices change?
A11) Generally, between midnight and 1 am Seattle (Pacific) time for scheduled deals. Price matches can change at any time.
Q12) I don't like the way Amazon does things.
A12) email jeff@amazon.com . He probably won't read it, but one of his assistants will and who knows, maybe it will be the catalyst for change.
