That last Canon Rebates expired on March 20th(as scheduled). Canon typically offers rebates once in Spring and once in Fall, but there have been exceptions.
Generally Rebates offer the most value on lenses, I just purchased a 60D on last day of the rebates and actually paid more than if I had purchased prior to rebates kicking in.
Canon rebates require participating retailers sell at MSRP, prior to these rebates most retailers were selling well below retail.
But the Earthquake and or panic buying has driven up the price of many cameras. The 60D street price is about $200 more than it was mid February.
