Folks I bought a Chromebook an Walmart a few more moths ago but decided I wanted a different and cheaper model through Amazon. Took it back on day 13 no questions asked. Just know the return policy of your retailer. Best Buy, Walmart, Sams, Costco (90 days). Keep your receipt and don't trash it. Hell you don't even need to leave the parking lot. Just open it up and if you don't like what you see take it back!
Go read the AVS Forums and you will be amazed at all the people that go through two or three 65" HDTVs until they find one that has just the "perfect" colors or just looks right in their Man Cave.
I plan on preordering 3 or 4 from different retailers and hopefully one of them will meet my specifications. The others I just won't pick up and cancel the order or return. Pick me up one or two brick and morter and at least one online seller like Amazon.
Oh, and buy it with a decent credit card so you get the extra year warranty protection free.
