Actually, the Amazon bit is a great point. Some of the best prices are from these online resellers that do NOT charge tax. The tax is a greater amount than the discount. Also, the low end MBP goes for $1650 brand new on a few sites if you are willing to wait for a $200 rebate. Still $1850, with no tax is as good a deal or better than a student discount. Then, two months down the road, you get your rebate and use it for some upgrades or software.
I always wanted to buy from Apple and did. But recently someone pointed out just how much cheaper one can buy Mac notebooks from resellers like Amazon, MacMall, MacConnection, and etc.
Probably have the itch so not going to be willing to wait. Good luck whatever you do!
