One of the best designed web hosting web sites I've seen. Very pleasing colors, beautiful smooth design, fonts that are easy to read, great images, easy to use navigation and order process.
The only critique is that this page gives a 404 Error:
EDIT: Actually, I will also add this: you have 2 different coupons that give 2 different discounts. In my mind this is a bit confusing for the potential customer because obviously he would want to use the larger discount coupon. Why not run 1 promotional coupon at a time? Or does it apply for different services?
