If you do a search for "digital camera" on Google.com, Web's top search engine, you'll get back over 7 million page results.

Refine your search to a specific model, such as HP Photosmart 935, and you get back 137,000 page results. Now do a search on BestBuy.com, CircuitCity.com, and Amazon.com and you'll only find it listed one time, and on that site it costs $60 more than I paid for it at Target.

Even though web makes it easy to search out products we want to buy, sometimes that mountain of information makes it almost impossible to find best deal.

To solve this problem there are "personal online shoppers" which help you seek, find, and comparison shop multiple offers for just about any product you want to buy, online or offline.

An online personal shopper-type service enables you to log on to a single site, enter product details you want to search, and then have website give you back a list of prices and places where you can purchase item.

The personal shopping assistant sites that rate best don't accept commissions for sale of items through their services because getting paid based on what customer buys would eliminate unbiased product comparisons.

The best services make their money by selling targeted advertising to merchants and only displaying products in their search results based on price and features.

Besides simple International White Pages web sites, there are many companies that are masters of locating personal information. Say you used to live overseas when you were a child and you want to see how your best friends from primary school are doing in their lives. You can find out their address, email, and phone number, even about their personal history, like whether or not they’ve got a criminal record! Some might perceive this as an invasion of privacy, like ‘Big Brother’ in book ‘1984’, but if one’s intentions are true and positive, I think this can be great for finding buddies, loved ones, and relatives.
