If you have GS credit go find one with two GTAV and a Diablo 3 today, buy them and trade the GTAV and there ya go.
No GS credit, only do the amazon.
Dont mind paying 35 out of pocket though so might still try and do that. 54.99 per, so 105.99 after b2g1, whats the TIV for gta v there? Higher at best buy?
Edit, doing the math of trading in to Best buy, 40.50 trade value puts it at 39 bucks for diablo 3 after taxes.
Too much effort to save 10 bucks.
