Blockbusters return policy gives you back store credit for the value of the purchased game and that store credit can give you another buy one get one free. so you can get three games for the price of one. Found it out accidentally 15 minutes before the game stop offer ended.
watch out though...
i dont recommend it its not worth it. it takes forever for you to get popular games i waited like 3 months to get bioshock than i quit and got it for PC...
its not worth the price its better to get a more reliable plan elsewhere.
