that is the LAST piece of hardware I buy at an Apple retail store!!!
Just spoke to them, bought a 20" cinema there on Apr 6th. The will NOT honor the price and credit me back, quoting their 14-day policy.
Meanwhile if I had bought it from Microcenter or CompUSSR here in town, I'd be looking at a nice $200+ tax credit because they have the industry norm 30-day price adjustment policies.
WTG apple.
