Hey everybody, I'm returning to this old (2 years?!) post to report that I finally developed this a little further by implementing a very basic shopping cart system for my frstcomputer.com gopher hole using PHP. If anyone here is still interested in the concept of a functional order-taking system for gopher, maybe give it a try? I do still have a few stickers. (but also... Plan 9 Cyberdecks)
