Deal Advice please (PS4 games)

Im wanting to pick up diablo 3, madden 15 and Destiny next month.  Any advice on how to get these three as cheap as possible???

Best buy promo for madden 15 , I don't know the details on it but it's in the deals forum. Hope this helps

Well I think you have GCU so besides the madden deal above Bestbuy is probably your best bet unless you have games that take for a lot of credit at Walmart. You get a 50% boost there during a upcoming promotion. You need 2 games as well.
