If you do not already know or use this price-portal, you should think about doing so. The principal idea behind Kelkoo is that they are gathering information upon a lot of different products that can be bought online for the users to have free acces for informational search. It works in a way that you can choose the category of interest, then you make a search input, fx. the name of some popular DVD or some CD player. When you have made a search you get an appendix showing all the available stuffs matching your search. The appendix is ranked so that you can see the price and how much it cost to post your order. Personally i have often used the english version when i have bought music and movies online, simply because that i do not know so much about the english market. The only negative thing about Kelkoo is that tey cannot have all the dealers i their system, so when you search on this machine it does not mean it is a waste of time if you do not find the item you searched for. This favourite machine is functioning very fast and is also easy to use. So as an online search-option i will gladly refer using kelkoo.dk
