There is another deal site that I wanted to let you all know about. The name of the site Become.com, and it is not only a site for shopping, but you can also research products on it as well.
There is a search box at the top of the page where you enter the product that you are interested in, you can then choose to shop or research. You can narrow your search results by searching in a certain price range, by color, brand, store, or category. So, say for instance you needed to purchase a 1 gallon gas can (you never know, it is always good to be prepared for emergencies), you would type that in the box. If you were looking for a 1 gallon gas tank, you would type that in and get search results for that.
