Kelkoo.com was founded in 1999 by Pierre Chappaz and Mauricio Lopez. Within 2 years of launching, Kelkoo became Europe's largest e-commerce website after Amazon and Ebay and the largest e-commerce advertising platform both in the UK and Europe by merging with Zoomit, Dondecomprar and Shopgenie.
In April 2004 Kelkoo was acquired by Yahoo! Inc and is now a wholly owned subsidiary.
Electronic commerce, e-commerce or ecommerce consists primarily of the distributing, buying, selling, marketing, and servicing of products or services over electronic systems such as the Internet and other computer networks.

Credit card companies do not want merchants to charge credit card users more than they charge other customers, even though the merchant pays a fee of 2 to 3 percent (merchants negotiate an exact percentage with their banks) to process credit payments. In some countries this fee may be significantly more. If customers were responsible for this fee, it would often discourage credit card usage.
The credit card was the successor of a variety of merchant credit schemes. It was first used in the 1920s, in the United States, specifically to sell fuel to a growing number of automobile owners. In 1938 several companies started to accept each other's cards.

From the merchant's view point, the transaction, if it is made using a bank credit card, is often much more secure than receiving payment with a check or carrying an unpaid balance because the issuing bank commits to pay the merchant the moment the trasaction is verified. The bank charges a commission to the merchant for this service and there may be a certain delay before the agreed payment is received by the merchant. In addition, a merchant may be penalized or have their ability to receive payment using that credit card restricted if there are too many cancellations or reversals of charges.
