CompUSA! CompUSA has been a favorite store of mine for a few years now. They sell everything for your computer needs from desktops and laptops to software to accessories. They also have plenty of media for your PC gamer or other system gamer too. They also sell TVs and DVD players too.
They have frequent in store sales and are often good online as well. Black Friday would be a good day in particular to watch their ads. They often have software free after rebate as well as some accessories. They often feature a computer system or two on rebate as well. You may find a line forming early for such things as a $100 after rebate computer. Other items such as the software though they can usually keep very well stocked! And if you'd rather order from home, verify the deal isn't a rare in-store only deal and you're set to order from home. You get free shipping with $150 or more unless they run a special.
Also, their rebates are better than ever now too! CompUSA has started an erebates program where you only have to type in the receipt or web receipt information, wait for the return period to end and then receive your check. Some manufacturers still require you to submit the old way. However, I have been doing CompUSA rebates and so long as you follow the instructions- I haven't had any problems with them that weren't quickly resolved.
