I put Super up in the store as a test, but now it’s testing me. If you go to the store page and click the “buy now” button you see under the book listing, a window will pop up and tell you there is a problem. If, on the other hand, you click on the book’s title, it will take you to this page where the button works just fine and you can make your purchase… Sigh… I actually dislike “almost works” more than “doesn’t work”, because the latter requires less digging.
