Last time i was in there, it's like they hover around you like a mosquito waiting for the right moment to jump in the moment you touch one of the products on display with a barrage of crap.
Because they're paid to do that =/...its no different than being in a phone shop
DVD's are uber cheap when stamped, I bet they do not supply them to make it harder to restore, meaning you are more likley to throw it out and buy another (well non IT people)
