I typically design to 975px wide these days. That allows someone on a 1024 wide display (the most common currently) to see the whole thing, even if they have a side toolbar. There is no reason to design smaller than that, and I personally don't like 'fluid' displays, which adjust to 100% of the browser's width. You can't fit any more columns of products in, so why make the site look awful on a screen at 1900px wide?
