It isn’t quite as good as a Buy One, Get One or BOGO deal, but a Buy One, Get One Half Off sale isn’t too bad either. (I thought about writing it BOGOHO, but if you parse that wrong… I’m not sure a BOGO HO is ever a good deal is all I’m sayin’.)
It is pretty simple, buy one of 67 select titles, get another one half off. Of the 67 total titles on offer, 32 are for PS3 and 35 are for Xbox 360. Prices range from $59.99 down to $18.11, and you’re limited to only two games under this promotion, with the discount being applied to the lower-priced of the two. So I’d recommend looking for games of similar price – the higher the price, the more you save. (And the more you spend, of course.)
Have at it.
