Did you get 5$ coupon with it? Save it, after New Year's Eve you'll be able to use it on top seller games. It will last for a month (until Jan 31st 2013.) and you can use it to grab 4.99$ games for free. Some of those games will probably be on sale in January and they will cost 4.99$
Do not buy 4.99$ games in next month and a half, go for more expensive ones. Because after Jan 1st you'll get them for free.
Last winter I got 10 free games that way (spent around 50$, got myself 15-20 games) and I'm not even American
