I also recieved a coupon for 10% off. I don't know what you recieved, but the fine print on mine said that it could only be used for "Tech" related stuff. It then listed a long list of related item groups such as Ipods, Laptops, Video Games and other electronics and their accessories. I just thought I would warn you in case you have the same one as I got. I would hate for you to bid extra high on a chip or something and THEN find out that you can't use your coupon. Check it out!
Peace and happy chipping,
Don
