Additional comment to Brad's:
There are also $750 off $1800 coupons (weekly? not as talked about as the "half off" $750 off $1500+ ones). Anyway, if you really want a Dell configured more memory faster processor larger HDD, etc. then you will be up to the higher base price (and still get to use a $750 off coupon). My point is that these "higher base price" coupons seem to have fewer restrictions on what you can and need to get!
Best of all is the (once per year?) $750 off $1500 with no limitations or pre-configurations. I used that in March to get exactly and only what I wanted (for a friend's graduation present). For myself I bought almost the same system but $75 more in the June $750/1500 offering because the 1 year at-home service was mandatory. I didn't try to get Dell to drop this. I also was prevented from getting the 7200rpm disk drive for my special.
