Sites that offer hosted shopping carts that are available for use with any website or hosting provider. Also listed here are hosted web stores and ecommerce platforms that include shopping carts as part of their functionality. The site offering the shopping cart, web store or ecommerce platform must host the software on the site's servers. If the software is hosted by the client's servers or by the client's hosting company servers then the site can not be listed in this category.
If the main service offered is general hosting with only a cart add on it would be better listed in Computers/Internet/Web_Design_and_Development/Hosting/.
If the site is selling the shopping cart software it would be better listed in Computers/Software/Business/E-Commerce/.
