when apple goes on clearance bby doesn't send them back to apple they have to sell through them. so this was the time i would (i was a ppm before i quit few months back) mark down the older models for my employees because this was the only time i could. during this time and with open box was really the only times you could price adjust apple stuff. the accomodation even sucks on apple.

so i would say wait till new stuff comes in because as soon as apple announces new stuff its in the store like 3 days later. also don't forget the PSP is different for apple product. there is not ADH on it also rarely will it get junked out, usually they fix the stuff continously.
