I am looking for a prepackaged (free preferably) shopping cart that can handle multiple stores on one database and one installation... for example I sell someone a store and they get a login/pass for the existing shopping cart program that allows them to manage the store (seperate from the other stored) by adding items, checking orders, etc.

Does anyone know of any scripts like this? PHP would be a plus because I no experience with ASP.

It seems that you are looking for an Online Shopping Mall system. You can find some scripts from http://www.Hotscripts.com. If you like PHP, try http://www.hotscripts.com/PHP/Scripts_and_Programs/E-Commerce/Online_Malls/. If you like perl, try http://www.hotscripts.com/Perl/Scripts_and_Programs/E-Commerce/Online_Catalogs/.

Hope this helps.

i would seriously look into miva for this.

i have been their since the beginning with them. Their new version 4 is bitchin. lots of new features like inventory management, and affiliate software... lot of bang for your buck with miva.
