Price Watch and Price Grabber are places that do price comparisons. You actually buy from the company listed as to where you can get it for that price. My husband and I always go to these sites to find the best buys and have never had any problems with the companys listed with them. Most of the time Dave will shop locally to see what the price is and then go on price watch to find it cheaper.
Doug is right about the refurbished too. We have bought refurbished in the past many times to save costs and had no problem. Good luck in your search. Glad to help out.
