I'm going to USA next month, specifically to LA, California. I'm planning to buy a 15" 2.0 GHz 2011 mbp. On the Apple Store, the price showed is 1.799,00 $. After I make the "virtual buy" and enter the ZIP Code, the price raises to 1982.40 $ because of the Taxes. When buying on a AppleStore in person, is there any other extra charge they make? Surfing on this forum, I found a thread about different prices on several retail stores: http://www.appleinsider.com/mac_price_guide/ 1. Why this sites sell computers cheaper? 2. There's a MacMall store in Santa Monica, should I buy there? (I save 135.51$) 3. I read some complains about online ordering with MacMall, but shopping in person could be a different story? Please if you have some advices, anecdotes or something i'll appreciate Thanks!
