I think we should have a section of the forum devoted to reoccurring sales times for tv's. So Labor day, Black Friday.... then general sales.
For instance I just caught the LN52B750 for $1,899 which is the lowest I have personally seen it. Looks like due to getting a jump start on labor day sales.
Until then post your labor day great sales in this thread! Be on the look out and try to give people a good heads up.
