Just a heads up if you are contemplating getting a Roku or even thinking of picking up additional units for their other televisions. Right now Walmart is clearing out almost all of their older models are prices that are very tempting. This is an in-store deal for U.S. customers only and not on their website. This appears to be nationwide. I've been to many Walmart stores in my area and the quantities are still pretty good.
I love my Roku. It offers hundreds of free programs and there are new channels added all the time. It's a great time to buy a Roku now at these cheap prices. An excellent idea to buy and hold for Christmas.
