Yes, there are lots of comparison shopping websites on the Internet that can help you to find the BETTER price, but normally, one site can't cover everything and you won't necessarily find the BEST price. You could waste lots of time checking all of them, one by one, making price comparisons.

Instead of jumping from site to site with a different interfaces and commands. Best Price compares up to 16 of the MOST popular comparison shopping sites simultaneously (and this number is growing all the time). These sites include:
mySimon, DealTime, CNET Shopper, PriceWatch, Walmart, Yahoo!Shopping, AOL@Shopper, Amazon, MSN eShop, PriceScan, Excite Shopper, iBuyer, Nextag etc.

Best Price provides a familiar and intelligent interface for pre search and a powerful set of tools and functions for price comparison.

For example: The user can select from pre-set or user-defined categories of search engines to search from. The user can use a query wizard to conduct an advanced search without any knowledge of "Boolean" operators or complex database language. 

Best Price has features that can not be found or performed on a Web based search tools. For example, it save searches in Excel, HTML, or other formats. Also can save searches for later use or modification. Even share online purchase information with your friends and family members

It's incredibly software enable consumers to search the Internet for any product or service without having to visit a single website and receive search results by the lowest price. Unlike traditional web-based price comparison services (i.e mySimon.com - Priceline.com). Best Price is not subject to obtaining information from an internal database, instead search the Internet, scanning ten's of thousands of merchants for the lowest price simultaneously! Guaranteed to save you Time and Money!

Consumers don’t realize that price comparison web sites do not provide targeted pricing and are limited to a select few merchants, paying the comparison service to list their products. Best Price has no limits as to who and where it obtains price quotes. Also some individual search engines are particularly effective and sophisticated, none are entirely comprehensive. Many use only a small database from which to search. And, the database may not be update very often.

It is estimated that nearly 80% of online shoppers will visit more than one web site before making a purchase according to NPD Online Research.  Perhaps Web users have discovered what the NEC Research Institute has found and that is, individual search engines cover only a small portion of the available Web, and their coverage provides a low percent of overlap.

Best Price search more than one search site at a time and provides BETTER PRICES and MORE SEARCH RESULTS more quickly.
