Well there is perhaps a way. You need to find the flips from gs buy 4 for ten deal that will flip to target during their 100% promo deals. Then take the target credit and buy bayonetta at target while price matching gamestop. Take those to bb for $33 bucks each assuming it doesn't drop.
1. Buy flips from gs sale (4 for $10) that will flip to target
2. Buy bayonetta while price matching gs
3. Trade into bb for $33
You could potentially save yourself about half price depending if there are any good flips out there. I havent looked myself.
What's going on at Target that makes Bayonetta 2 flip to BB for a profit? GameStop shows it as $35, so trading it for $33 doesn't make much sense to move credit, IMO.
I maintain just make a dummy GS account, get a B2G1 coupon, and get three of the big-name titles for $100, then trade them for $129 at BB (since those games are going to be $43.20 each). That, or if you do a bit of searching, there are probably some good flips to BB that'll get most of your credit there without getting Target involved.
