They have about 200 sets remaining with 10 minutes to go for the deal to end. They are probably not going to sell out before the deal ends.
Probably the deal was not out there for people to see. It is still a very good deal for the TV.
I posted this deal in the SAMS thread over 12hrs ago, its been known and been listed as "doorbuster" from dell since yesterday.. The price has been this as mentioned for past 2 weeks from multiple retailers on and off. Walmart, Amazon, Sams, Dell all have/had this.. If Costco had this TV, then id buy it since they include the second year warranty...
