Canon used to run two rebates a year, Spring and late Fall. With the poor economy over the past few years, it has been one rebate after another. Obviously, Camera makers want to stop that because it hurts their profit.
The economy is improving slightly in the USA, so Canon is going to slow down on discounts and rebates to see if they can still move inventory. If not, expect some big rebates. Even the sale in the refurb store has far lower discounts than we have been seeing.
The few weeks before Christmas is typically a time for low prices, so save up to get the gear you want and be ready to jump quickly for a one day deep discount sale. By signing up at Canon Price Watch and entering your target price for a item, you will get a e-mail a few minutes after it goes on sale at your price.
