Discount Shopping and Store Reviews by Real People at ResellerRatings
There are a few companies in New York which try to pull a scam by advertising at a very low price, but then telling you that all the accessories normally included cost extra. Or they try to sell additional items at a high price, and if you won't buy they tell you the camera is out of stock and your order is cancelled.
B&H prices are usually a good guide, and anything much lower should be viewed with suspicion.
