I appreciate all the good advice, and I decided to purchase through American Airlines e-shopping. 1 mile per dollar spent isnt too bad without an affiliated credit card and works out to approx 5,600 miles.

Also, no need to purchase through CostCo as there are none in the Pittsburgh area and my previous Dell desktop has given me ZERO problems in 6 years so Im not worried about returning at all.

Thanks again for all the quick advice I do aprpeciate everything!
