In S Fl , CompUSA has quite a few B&M stores in the area, I end up buying most of my parts from them. Their prices are inline with most e-tailers.The only issue is they aren't always up to date with the latest hardware at the store closest to my house so I have to go farther to get what I would normally get online. Paying the taxes is usually better than paying the egg's "updated" shipping charges.
CompUSA is not the same company today that they were up until a few years ago. They essentially went out of business, and TigerDirect acquired the rights to the name, logo, and web site. They are now TigerDirect's B&M storefront.
All of the former TigerDirect stores in the Chicago area are CompUSAs now, and the prices are (usually) the same as the prices on TigerDirect's web site.
