Walmart cuts prices on two LED HDTVs, but you can still find them cheaper online.

Walmart has announced a number of price "rollbacks" (to use its term) on HDTVs and home theater products today, including on a pair of LED sets. The only problem—the rollbacks don't always go far enough.

For instance, the retailing Goliath has cut the price of Sony's 52-inch Bravia KDL-52EX700 (pictured) to $2,058. But apparently Walmart didn't get the memo from Sony that it could lower the price further. A quick Google search shows that multiple retailers are selling the same TV for $1,979.99, including SonyStyle.com. Even more striking is that the new Walmart price for the LG 47-inch 47LE5400 is $1,568—but it's just $1,377.98 at Amazon.

Offering a product for nearly $200 more than the competition is not usually the Walmart way. More typical is the actual deal you'll get if you want Vizio's VSB200 sound bar system. While the online price is generally $149, you can get it at Walmart for just $98. And that Magnavox Blu-ray player that seems to be offered as a "doorbuster" for every major holiday is once again on sale, this time for $79.
