Every item generates a "Buy Item" button under the item preview avatar in the wardrobe (the one on the right that shows single, selected items), even while the wardrobe knows full well via filters that I have the item (such as, viewing "My Items"). I double-checked with Account Search to make sure they're still there, as well. This is occurring for any random wearable I look at, of any age or providence.
