I'm new to the ebay APIs so am still finding my way around. I am using findItemsByCategory to create a list of available items for users of my app and using GetItemStatus to check if the cached items are still available. However, I noticed there are many listings with quantities greater than one. Most importantly, and unexpectedly, if the quantity remaining is zero ebay still classifies the listing as live even though nobody can buy the item. It's not efficient to call GetSingleItem on everything, so anyone have a better solution to get the remaining quantity fora large number of items?
