I sell a list of items and need to pull them from stock. The SKU tells me where they are. At the moment I need to visit the item page of every individual item to get the SKU - it doesn't seem to show anywhere else. It would save lots and lots of time if the SKU was shown on the "Auctions I've Sold" list within "My Ebid".
Alternatively, including it on the printed copy of the Invoice would mean that it could also be used as a packing list - that would be even better.
