Curious

I don't actually have an Entertainment Book, but I was wondering if the $50 off $500 was stackable with the 15% or 20% off coupon code that Dell is currently running until June 2nd? There are other coupons such as $25 off $500 and $30 off $800, but when you enter these codes, the percentage coupons disappear. I have noted on the Dell website that there are certain coupons that are stackable with the percentage coupon code and I was wondering if the Entertainment Book was one of them.

Thanks for the info.

Incidently, does anyone have an Entertainment Book with said code to give away?
