All the vendors are doing the same exact thing, Amazon included.
The price of the 60D was $888 yesterday and it is still $888 this morning since they jacked the listed price up to match the $100.00 rebate.
They are all guilty of Scam marketing IMO. But nothing out of the ordinary since these vendors think your ignorant.
Amazon's price is 1,457 and Adorama's is 1,479. So not, it's not every retailer.
