When you finish building your database via Go-Cart, it is then exported to an HTML file. At this point the second part of Go-Cart is employed. The second part of Go-Cart consists in JavaScripts that enable the end user to order products from your website. Add parameters to items, e.g., allow the end user to specify what color or size they prefer of a certain item. This feature also allows dynamic pricing of items.
All upgrades are free to registered users.
You don't want a remote site to host a shopping cart for you, since this can be very expensive. Go-Cart has a cart building program. The only thing that you need to do is have access to a send mail program. Almost anyone who runs a website has access to a send mail program, but even if you don't, many remote sites will let you use theirs for free. Also, unlike CGI shopping carts, this script executes on the user's computer.
