Carts or shopping carts can have many forms.
Some websites offer only a few items for sale. Instead of maintaining a large website, it's best to use "Buy Now" buttons from established services such as PayPal.
When you sell many items, a shopping cart site is the best solution. We install and configure a shopping cart created and supported by osCommerce. This is a well-known and supported PHP software that uses a database to keep track of all the items. Unlike other shopping carts, the software is FREE and has no charges for its commercial use.
Once installed, you have a very powerful program that keeps track of sales and even checks UPS and USPS shipping servers to figure the correct shipping costs. You're able to update prices, add items, pictures, and even inventory the Items you stock in your online store.
An example of a cart : www.needleandthreadoftomball.com
The store owner is in charge of updating the items and uses her store's computer to manage the site. (She is just getting started so all the items have not been added yet.) We installed the site, maintain the server, and provide weekly backups of the e-mail, database, and webserver.
This is a screen shot of the control panel that is accessed via the Internet once the cart has been installed. This type of control makes it easy for the store to be updated, products to be added or deleted, and manage orders. Total store management can be performed from any location that has Internet access.
