• Answer:

  Click on the Help link at the top of the page. Then click on Contact Us at the right side of the next page. You can Live Chat with a rep who will stay with you until your purchase goes thru with the add-on item. You just experienced a glitch in their ordering process. Their system was not recognizing that you had $25 in your cart. But it might be that one of the items in your cart was not part of the "add-on" promotion and your purchase did not qualify for the add-on.
