THIS DEAL IS NO LONGER AVAILABLE. I SIMPLY UNLOCKED THIS OLD THREAD AS WAS PLANNED ONCE THE EMAILS STARTED COMING OUT.
Best Buy has a promo running where you get a $10 savings code for each $10 or more order you place with in store pickup (maximum three total transactions).
The orders need to be $10 or more pretax and so ideally to maximize gains you can get $10 eShop or PSN cards (cannot find physical $10 XBL card correct me if I'm wrong). With a maximum of three orders just place 3x single $10 card orders and then we all should get the credits in January and can essentially buy $30 more credit making it $60 credit for $30.
I am sure there are other good ways to use this promo but this seems ideal for most here!
