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."

Has anyone used an "upfront mortgage broker" to secure a home mortgage?
Q. I was wondering if anyone has used these UMB's and if they have could you provide some feedback in terms of comparisons to a regular or retail broker? Can you negotiate price, how much did it cost in comparison, customer service???

A. I'm not sure what you mean by that term. I work for a mortgage broker - there are no "up front" fees if that's what you mean. All of them will be required to give you a Good Faith Estimate "up front" too. Hope that helps, email me with questions at robert495713@yahoo.com.

Is it worth paying extra ?
Q. Hunting around for car insurance, and could just go with the cheapest on a money comparison list - but is that the best option ? For a bit (to a lot!) more some insurers include benefits such as courtesy car & free legal service etc. But is it worth paying the extra for something I might not use ? I notice Direct Line are refusing to be part of these lists because they say they are not accurate comparisons as cheapest price is not necessarily the best deal. Now I know why it's called confused.com! Can anyone help me ?

A. I wouldn't pay for the legal service, it's highly unlikely that you would ever need it and if you did all you need to to is visit your local CAB for advice. I think the courtesy car is a good idea, I have this on my direct line policy as I would be lost without a car - I live in a village with no bus service - so I think the extra I pay is worth it and it's not much anyway, about 20 a year from what I remember
