It's been a long couple of weeks of coding, but I've got most of the store out of the way. We have a few minor things to add in:
1. I need to code a parent link into each page to easily navigate to the parent page (and not using the javascript "back" code)
I went ahead and added a "most popular items" page; it required scouring cafepress for each order ever processed, but it's all in place (and will be easier to keep maintained).
I'd like to thank Curse for the idea of a most popular items page, and Glider for various suggestions.
