Priceshout, a self funded UK based company, has just launched a price tracking/price comparison/social shopping/wishlist website. Think of what Kelkoo.com might have looked like if it had been created in this web 2.0 period.

Basically it allows you to build up a personalised price comparison mini-site that tracks the products you are most interested in, and enables you to search, sort and filter the products using tags and other constraints (such as currency, stock level, price range, popularity etc.).

You can then monitor the searches you created in your RSS reader which in turn then alerts you when new results are found or as products’ details change.

Then on the server-side, PriceShout’s software automatically fetches and updates the details for your products from their partner supported stores (currently 15 stores are supported, and they are looking to expand this number to 30 by next week).

The site has developed and evolved over the past 12 months and been in a private alpha for around 3 months.
