Why is the item I just purchased still showing as "available in stock"?

Sometimes we have a few of an item and you may see the item that you purchased still available for purchase (until it sells out.)  

 For items available in multiple quantities, our inventory update through Google's photo inventory updater may take hours to days. If the next available item is identical to what you've purchased, the listing might not immediately update. This is because each signature is unique and although the product image remains the same, the actual signature you receive will differ slightly from that shown. We assure you, all signatures are original, hand-signed, and authentic and we do not sell any that are machine-copied.
