Two different replies for the same question regarding the iPad 4...
Not sure where the other guy is getting his figure from, but I pulled mine straight from the 'Black Friday Preview Ad" off Best Buy's own site. Show's the Retina iPad receiving a $40 discount on Friday. Granted, it's the A5X version, wouldn't make sense for them to discount the newer model more than the older one. My own assumption would be that the Reward Zone Silver Member sale was its own separate thing. But who knows, I could be wrong.
