"Dozens of Professionally Designed Themes"
so says the CCSCC sale page. How am I able to access the "dozens"? I find 13 available in the add-on purchase list. And when did they go up to $9 each?? What am I missing?

I see 21 in my program, and then here are 12 more (as you stated) https://www.coffeecup.com/store/themes/shopping-cart/ and if you purchase in bundles they become cheaper, such as https://www.coffeecup.com/store/themes/shopping-cart/bundle/after-twilight-pack/

And of course, there is the Designer that is coming next week.

Some of the templates for the 'other' shopping carts out there, can cost significantly more than the prices Coffeecup charge.

Design is very much a matter of personal choice and the forthcoming designer will hopefully allow the SCC users to create the designs they actually want, rather than using the same generic designs that everyone else is using. The designer will also allow users to match the shop more accurately to the rest of their web site design.
