On the internet, a price comparison service (also known as shopping comparison or price engine) allows individuals to see different lists of prices for specific products. Most price comparison services do not sell products themselves, but source prices from retailers from whom users can buy. In the UK, these services made between £120m and £140m in revenue in 2005 , and is growing at an annual rate of 30% to 50%.

History

The internet boom of the late 1990s made price comparison profitable.

Price comparison services were initially implemented as client-side add-ins to the Netscape and Internet explorer browsers, and required that additional software be downloaded and installed. After these initial efforts, comparison shopping migrated to the server so that the service would be accessible to anyone with a browser.

Services are now offered by websites dedicated to price comparison and by major portals such as Yahoo!.

Shopping

In the late 1990s, as more people gained access to the internet, a range of shopping portals were built that listed retailers for specific product genres. Retailers listed paid the website a fixed fee for appearing. These were little more than an online version of the Yellow Pages. As technology has improved, a newer "breed" of shopping Web portals is being created that are changing both the business model and the features and functionality offered. These sites do not "aggregate" data-feeds provided from the retailers, they search and retrieve the data directly from each retailer site. This allows for a much more comprehensive list of retailers and the ability to update the data in real-time.

Generic portals and search engines launched similar services and companies that stood to benefit from increased internet shopping (especially credit card and delivery firms) launched similar sites. Many of these services have since closed.

What happened to www.cairo.com, the website that provided price comparisons for local brick&mortar retailers.?
Q. I used to search out the local ads on cairo.com instead of reading the circulars that are printed every week and included weekly in the newspaper. The URL was www.cairo.com, but it disappeared one day. (now you get a travelogue for Egypt!) I thought it was a great service. Wonder if there is another one out there like it. I know about the websites that do the same for online retailers, like PriceGrabber and Froogle...but I want to know if there is another website that checks and compares the local brick-&-mortar retailers sales ads each week.

A. I guess it's gone. This is a quote from an investor of the old cairo.com: "...when the new CEO sliced and diced the data, a more valuable business came to light - so we're moving in that direction which we think will be larger and more exciting opportunity -- we'll be able to tell you more about in a couple of months."
