I bought a nice 1.25 Ghz Mac Mini with 256 RAM more than a month ago. Suddenly, I started realizing that it needed more RAM. "512 Mb seems enough" I though, so I started saving money for RAM, and also AirPort and Bluetooth. The online store said it costed $75 for 512 Mb RAM, and $100 for an Airport+Bluetooth combo. So it seemed clear to me that it was going to cost $150 plus an installation fee. I took my Mac Mini to the Clarendon Apple Store in Arlington, VA. A young guy, which seemed new, told me that the Airport+Bluetooth combo costed $100 (which was what I expected), but then hi told me that the 512 Mb RAM was going to cost $150 plus $30 (installation fee). I was like "what the f*ck???!, but on the online store it says $75 for 512 Mb RAM". His explanation was that when you order online they keep the 256 Mb RAM, but in the store they return you the old RAM. I walked out the store very sad, his explanation made sense, but still... $280 for RAM, AP, and BT, that's too much, it's more than half the price of the computer, and all the magazines that I've read say that 512 Mb cost $75. I have though about some alternatives, please, somebody tell me which is the best one. a. Call a different store, and check if that was the right price. b. Buy a 3rd party memory (~$60) and install it by myself (I have no experience on installing memory, and... is it going to breake the warranty?) I would have to take the Mac Mini to the store anyway to have BT and AP installed. c. Pay $280 as the guy said. If you have any other suggestion, please tell me. Thanks on advance.
