Costco already has this model (VIZIO XVT553SV) . The 55" runs for $1799. They also have the RazorLED 55" for $200 cheaper.
Nobody pays retail anymore. You do know that $2200 is MSRP. The only ones who still sell at MSRP are Nintendo, PS3, and XBox 360.
You may want to add that to your dissatisfaction of the price.
