OK, I just bought the LED one for $169. In addition to the cash back promos from credit cards, you guys can ALSO get an additional 7% cash back by doing what I do. I have free accounts at both RetailMeNot.com and Rakuten.com. These sites are great and save me hundreds a year.
Here's what to do:
1) Add the item at Wallmart into your cart.
2) In a different browser window, visit Rakuten.com, type in Wallmart, then click the link for 3% cash back (currently offered as I write this)
3) In a different browser window, visit RetailMeNot.com, type in Wallmart, then click the link for 4% cash back (currently offered as I write this)
4) Finish checking out. Bingo! You just saved an EXTRA 7%.
Doing this will ultimately get you an extra 7% cash back, plus whatever you got from AMEX or Chase offers.
