Same thing happens to me often supervij.
My receiver, t.v., digital camera, printer, dvd recorder, dvd's were cheaper a year or a few months after I bought them.
The one that really burned me is my tv. About six or so months after I bought it, there was a price drop(~$1000)including a free stand($700 value)and free sat or cable box
.
I find that if I keep waiting, even up to a year with no special or price drop, I just give up and buy the product. Then weeks or months later the price drops. It always happens!
