Which mac model would you like to buy?
1. Go to
AppleInsider's pricing listto compare the prices from different vendors.
2. Go to
evreward.com to search the best points/miles program in your interest.
3. Go through the best program's website to buy the mac at the selected vendor.
For example, I was looking for a new mac mini recently. The best price that I could find was $769 (with Amazon prime's free 2-day shipping) on Amazon.com. This price beats the best education price on apple store. I went through US Airway's shopping mall to place an order on apple online store with my SPG AMEX credit card (I didn't buy the apple care becuase SPG AMEX would cover one year of warranty in addition to Apple's default one year.). So in total I could get 769 US miles and 769 SPG points.
Purchase on Macconnection and MacMall might be sale-tax-free to some states residents.
