I need a shopping cart with simple plugin or ext of some kind that allows me to export items in mass from the cart and list them on Amazon and/or ebay. I have access to hundreds of clients seeking web design and just need something that will allow me to build a simple sites. Import items form a data feed to flush out the items the clients will be selling, while allowing them to add their own items as well. After this is done I want to offer a simple solution to export these items and easily list on Amazon/eBay etc. Any ideas?
