[quote name='camb1986']I know this is pretty silly, but is there any way to get each game at a different location, but still get the b2g1f? Three gamestops in my area don't have all the three games I want in one single store.[/QUOTE]
This will work, as I just did it. Got 2 Vita games near my work, exchanged them and got the 3rd Vita game in B2G1 free near my home at a completely different GS.
Actually lucked out, as I got Unit 13, UMVC3, and Rayman Origins for $67.86 on a YMMV move. See, they sold me Unit 13 at the Spring Break sale price of 27.99, but when they returned it to trigger the B2G1, for some reason it returned it as normal $34.99 price. So, while the bundle of those games should've cost ~$75 after tax, I saved a little bit thanks to some random luck. And GS includes a free online pass for Unit 13, so I'm even happier.
For Vita owners looking strictly for Vita titles, this may be the best way to roundup your desired titles, given you don't mind a little gas and time.
