I guess you can tell I've been playing around a lot! :-)
So, I've tried two different ways, the first way here: http://www.lotuskey.com/wordpress/category/prints/
And the second way here: http://www.lotuskey.com/wordpress/prints-shop/
The first way is as I described above - each product is put into its own post, which I then link to a category (used only for products) and then have the link to that category for easy access. This way it goes through my feed as well as having a static location. [I feel I should note here, I am loading original images from my desktop and creating products via your plugin, then directing the link to the appropriate item in Society6. I'm not a hard-core coder, so I'm not sure if any of this has any bearing on the outcome of things, but I thought it was a detail I should mention.]
The second way was something I just tried, to see if loading speed was faster. I created a page and inserted the Shorthand code to show all items in the shop.
The load speeds seem to be the same. Maybe this isn't a code issue and is just a loading speed issue on my end? I'd have to ask other friends to check it out and see how it loads for them. The scrolling just seems a lot more jerky than my other "display category" link: http://www.lotuskey.com/wordpress/category/portfolio/
Hope I've been more help than hinderance! Thanks again for all the great (and quick!) responses!
