The link for the "Pentium 4 2.80CGHz HT" is incorect as well as its price. They point to the 2.6C processor.
Also, if you don't mind, I have an idea. I was thinking of something like what newegg does, they have a "wish list" feature so that we can add all the items we want and see a final price. This is also useful because I can go back whenever I feel like, see my wishlist without logging in, and see the price. This way I can tell if the prices have dropped or not.
It makes it a lot easier when you know you have 2 or 3 weeks to buy a system and you want to keep track of all the prices. If you want to take this one step further, you can even allow people to have their wishlists critiqued because in General hardware, atleast two or three people everyday want their new system critiqued. Newegg used to do this as well but I see that they stopped putting links for the wishlists on their front page.
