How is the Offer quantity different from Inventory Quantity?
From my understanding, when an inventory item is added, it's quantity is specified. Then, on creating an offer for the same inventory item, the available quantity for the offer is specified again. My question is if I have to create an inventory management application, do I need to update the offer quantity and inventory quantity separately, using the **bulkUpdatePriceQuantity** call, after a successful sale? Or do these quantities update automatically? (I cannot test this on the Sandbox myself as I am getting internal error when fetching orders)
