I went to Costco last year on bf and it was absolutely empty. There is absolutely no reason to rush there as there are no early bird sales, and the items that have coupons are not worth going there at all.
Sam's will have that model for the sale. They are basically just rehashing the same sale that Costco had on this tv 1-2 months ago. Not very original on their part. This tv did not get a good review on cnet.com.
It is a Viore model#. It is a new model just made for Walmart. I have never seen this brand, but I read a lot of complaints about a Viore plasma that Walmart sold last BF.
