I checked and Costco, HH Gregg and Amazon are also around $1,899. Video and Audio Center, which sells through Amazon is at $1,497, and may have jumped the gun on a price reduction, which may go into effect tomorrow.
Interestingly, Costco's sale price of $1,879, $200 off, is good through today, August 20. If the price of this set is being reduced by Samsung they may reduce it tomorrow.
For what it is worth, I am actually interested in the 65" version, which has been $100 more than the 60". The spread has now widened to $500. Costco's price on the 65" ($1,979) is good through next Saturday, 8/27. These sets seem to be coming down, and I wonder if the 65" will be reduced next Sunday
