Canon has recently launched an instant rebate promotion for a few of its DSLR products. You can save up to $500 on lenses, up to $300 on a new camera, and up to $70 on Speedlites and accessories. Of course, only a select few products qualify for the rebate, and you might be saving only 10 percent off the original price. Still, the lenses eligible for the rebate are very good (for example, the highly praised 70-200mm f/2.8L IS USM), and if you've been lamenting the high cost of lenses, now may be the time to jump on these reduced prices. The camera and flashlight selections aren't bad either. Better get going though, because the offer only lasts until July 11, 2009.
