NewEgg.com is one of the largest e-retailers for computers, TVs, and other tech gear at reasonable prices. We've recommended it before as a place to buy tech for less, and we frequently check in with their sales and clearance section.
Based in California, its product offerings are similar to TigerDirect.com, and prices are comparable. It's a good site to check for price comparison when you're shopping for a new laptop or flatscreen. Check the rebate and clearance centers for special discounts and coupons before you buy.
