Here is a site that will cost you $10 for two months, but it provides a weekly list of the lowest-priced products at your favorite supermarket matched up with manufacturers' coupons and specials to save even more. You can even sign up for multiple grocery stores.

This site lets you know how much things usually go for on eBay and what's currently for sale there, so you don't over pay when you buy. Type in an item name for price comparisons on current and recent eBay listings.

2 for 1 here... Hunt online for the items you want at the most you're willing to pay. Create a wish list at the most you'd spend for each purchase. Then the sites search for the products, e-mailing you when they turn up your desired price or less.

Consolidate many travel sites to get you low airfares, hotels, car rentals, and vacation packages with a targeted search. You can enter details of your trip once, and then click on the names of the Websites you want booking buddy to search.

Enjoy!
