Haven't read the thread. But every year I have to chime in because for some unknown reason it gets so much love from the mathematically challenged. This deal is equivalent to 33% off full retail price, as target will charge full retail for most titles. Best Buy GCU is a better deal on any game whenever it is on sale, even if it's just $10 off.
It's a very like warm deal unless it stacks with a discounted set of games, which will be very limited in selection.
keep in mind that Best Buy GCU discount is not applicable anymore during black friday sales
