I was looking into getting an Mitsubishi DLP HD set and last week the set was a bit under $3000 on Amazon.com. Yesterday I looked at the same set again and it was reduced to a little under $2200. Today it's back up to $3000. Does Amazon just do unannounced sales like this from time to time ( I know they do on DVD sets) or do you think this was just a mistake that was corrected. And if I would have ordered it I wonder if they would have honored the price.
