Instead of looking for the "deepest discounts" I went with where I thought I'd get the best "overall" deal. Probably going to get disagreed with here, but I bought my 15inch at Best Buy because I'm a silver RewardZone member, plus I paid with my Amex after reading on here about the 1 year extra warranty with Amex. So now I get a 45 day return period, reward coupons, and 2 years of warranty...and I didn't have to deal with having a several thousand dollar product in the hands of a 3rd party plus let it be shipped (and hope that the shipper would handle my package with care....wow, can't believe I just typed that).
I feel good about getting it same day and walking home with it.
