Consumers hungry for a bargain on digital cameras can become bait. Some online retailers lure customers with cheap cameras, then call them to "confirm" the purchase. They then try to switch them to a different camera, or sell them overpriced accessories.
If the buyer balks, then you're treated rudely or the camera becomes
"unavailable." Those cameras can also be gray market cameras designed for overseas use, with no instruction or even a battery.
Consumer advocates recommend looking up websites on the Better Business Bureau sites.
