I have been buying some items from Logos that were in my Wish Lists, and when I was going through one of them I realized that it does not show when an item was already purchased. I had the Hermeneia Continental Commentary Series in my Wish List, but I had purchased it a couple of days ago. Wish Lists currently do not show that an item is already purchased. My suggestion is that if something is purchased (for example, when there is a sale, and so one does not go to the Wish List to purchase such item, since the link in email or blog to us directly to the product page), that it either a) the "Add to Cart" button that is seen through Wish Lists becomes grayed out after the product has been purchased, or b) the product is deleted from Wish Lists automatically. That would help those of us who (for example) go from one Base Product to a more expensive one and we forget that such an item was part of our purchase upgrade.
