Thanks for the update. It is most appreciated. With Drupal and Uber integrated as a cart it is hard to tell what part belongs to which program. Glad that you have clarified that for all of us. Will just live with the way it is.
The important part is to finalize the Alpha and move on to fixing the bugs in Beta. Then for stable release number ONE!!!
Here is an interesting cart that I came across today.
Perhaps you have seen it.
Keep up the good work and if PayPal works should have an operational cart soon.
