Don't forget the 3% fatcashwww.fatcash.com
(comes from fatwallet.com)
Also, keep an eye on fatwallet.com (forums, hot deals) for Dell E&A coupons, generally i search for Dell Home, or Dell coupons, sometimes ya just gotta read some of the dell deals that are going on, and find the coupon codes.
Usually at least once a week (seems to be tuesday's) there's a $35 off $300 purchase or close to it.
I ordered, linked from fatcash for the 3% off, during another 10% off promo, canceled the install, installed it myself. Sold off the 9700 128meg for $92 (buddy wanted it), so ended up with a smoking deal on my card.
