I saw this post in Quark’s user forums, and thought it useful:
Is it possible to create a shopping cart for a web site in QuarkXPress?
I think you need to add a website module to your site to do that. You can design the background of the store in Quark, but adding a module will handle things such as adding new items, setting prices, checking out, calculating shipping, etc. The one I use is called Zen Cart and is available to download HERE. You can design your entire site in Quark and them add the Zen Cart module to your web server and link to it from your web pages. It allows some customization so you can make it look like it’s just another page in your website.
