It's there, John.

The new storefront does not show you EVERYTHING an artist has for sale when you first enter the store. It shows only the featured items (typically the 30 most recent.)

To see everything you have to choose one of the other headings at the left, for example "Poser." NOW you can see all of the items. Jinn is on powerage's very last page. That's why it was hard to find.
