I was looking at this site :- http://www.testfreaks.co.uk/digital-cameras/fujifilm-finepix-s1600/prices/?tab=local i noticed there price comparison was by price runner , then i noticed on price runners site it quoted commission junction as there partner for doing the price comparisson. where are the best places so i can put a link on my site which will list say the top 10 local to your country places that keeps the price updated and perhaps also shows instock , out of stock etc.... does commison junkie offer this service or can you reccomend another or better ones for usa and u.k please.
If you plan to get paid, you can use one of the pre-built comparison shopping sites OR you can pull the information from one of the affiliate networks like CJ but then you would need to apply and be approved for each individual merchant and then you would need to download and process the product feeds to create the comparisons. With my shoe focused site (link in my sig) we do just that by pulling info from CJ, Google Aff and LinkShare. Doing real price comparison this way is a bit of a pain because the quality of the product data feeds varies widely between merchants. So you'll make less money by partnering with a pre-built comparison system on a transaction basis but you may net more money because you can launch quickly and you don't need to deal with building a system.
