Here's my experience with Best Buy, even though this wasn't planned at all, it may be successful for some of you, I suppose your mileage my vary:
Even though I originally bought the 65VT50 from Best Buy for $2,699 (with tax, $2,860.80 out the door) on 11/16, the Magnolia manager at my local Best Buy was extremely rude. He wouldn't honor the $2,599 price even though he logged onto this thread (he knew all about it, says he's an avid AVS reader) and basically told me even though it's been posted here by you guys, there was no way other Best Buy's around the country were selling the tv at $2,599. He was willing to let me walk and lose the sale over the $100, but unfortunately I caved, paid, and scheduled my delivery for the following Monday.
As I got home, and as I told this story to my girlfriend and a few other of my friends, it really bothered me (and them as they gave me their feedback) that this Magnolia manager was not in the least friendly, had nothing positive to offer, and was basically acting like a thug, so I decided to go back the next morning, to the normal returns/customer service area, and told them what happened the previous night. I told them I'd like to get a refund, not because I no longer wanted the tv, but my experience was horrible, especially for the amount of money I was spending. I said if that's the way he treats a customer at initial purchase, I could only imagine how they'd treat me if something went wrong with the television after purchase. The manager of the returns area offered to take the extra $100 off as a courtesy, but I told him thanks but no thanks, and they processed my refund. I'm sure if I haggled, and counter-offered that in addition to the $100 off, they throw in something like 3D glasses or a few blue rays, they probably would have done so just to keep the sale, but I wasn't in the mood to haggle.
So, I ended up going home and buying the 65GT50 off of Amazon. Sure, it's not the "top of the line" Panasonic, but the one sheet of glass, and the extra filter the VT has isn't a big deal to me, and I preferred saving a few hundred bucks and not paying sales tax. Amazon delivered one day after Best Buy was supposed to, brought it inside, installed the stand onto the tv, and I am extremely happy with my purchase.
