I bought a "custom build to order" from MacMall at a cheaper price than (Apple stoer educational discount + sales tax). They stock most configurations.
Looks like upromise rebates 5% from Macmall. Wish I had thought of that when I bought it!
My last Mac had a few problems and I used my Mastercard extended warranty to get a $320 check, so I wouldn't miss out on a year extra of warranty, it's like getting AppleCare for free!
