I agree, Amazon would have been the best option with fast prime shipping and return policy. They had it on Friday and Saturday for this price. I wasn't decided on this one then. But when I was done with my research and ready to pull the trigger on this one on Sunday, the deal was gone.
By the way, the lowest price I can see on this was $298. If you are using cash back, this offer has been the cheapest. So it is definitely hot!
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.
