Well i just went to my local Circuit City (in Springfield, PA - that's the springfield in delaware county....) and I had no trouble at all. I'd recommend that store, if you live nearby.
I brought the drive to the front, showed the lady the price. She had to call the manager (on the phone), and ask him if it was allright. She mentioned how there was a mail in rebate, but it didn't say how much it was and blah blah blah. Apparently, the manager told her to go ahead. She gave me the drive for $79.99 (after checking the ad carefully to make sure it's the same drive) When I asked about the 110% price match thing, she told me that it's only 110% if you buy the drive from CC, and then find it cheaper. At this point of course, I asked the obvious. "if i buy this drive for your price right now, and then come back in 10 seconds and point to this ad, can i get the full 110%?" She basically told me not to push my luck - she said that they don't even usually match comp usa, (and that she was being nice enough as is, basically)... Fine.
With tax, it came to $84.79.
As I finished up, she suggested that I check the company's website (Western Digital) because i may be able to print a rebate from there. Hehe - what a nice salesperson!
