[quote name='polishpride212']There is no exploitation in grabbing three games, scanning them, scanning a coupon, and having them ring up for free. The B2G1 was exploitation, but free games were poor design.[/QUOTE]
^This.
The free games "deal" required no trickery, deception, or funny business on the buyer's part (unlike the B2G1 which required CAGs to order games a certain way, distract employees, etc.). It worked like any normal transaction done with a coupon. The coupon only managed to take off enough to make the overall cost for the game zero due to a concurrent sale.
