Why comparison services appear? I can answer to help buyer check the price, shop & information as much as possible. Most of comparison services site such as pricegrabber.com, bizrate.com is good for buyer to get the many shops but sometime for me it's too much shop. Because if I'm buyer, I would like to get recommend shop, trust shop or popular shop over internet. If you see some shop as you never heard, will you visit and buy from them, No.

The comparison services have enough of buyer. Buyer just visits only site and see shop as they sell products. Buyer doesn't need to take time to surf again.

I would like everyone who are looking to buy some products please check the price, shop and other benefit as shop provide (shipping, special offer) before you buy. You will get the best as you want.

Don't miss this step I think it's very important when you looking to buy something. Enjoy you shopping with .
