I run GTC listings and use the eBay Out Of Stock option so that the listing is not ended when the quantity runs out it is just "disabled" until the inventory is replenished.
In SixBit, I tried setting the quantity to 0 and got a failed revision warning saying the quantity must be greater than 0 and lists the quantity as 1. This keeps the item available for sale and causes a possible oversell condition since the item is out of stock.
Am I missing a setting? In the profile I have the the "Use Out of Stock control" option checked.
