I'm helping my aunt set up her jewelry crafting with an online store. Because everything she makes is one of a kind, we set the wix store/products/inventory tracking to one per item, but that doesn't exactly function the way we'd hoped. Ideally, if a store of one-offs' item sells, the store would automatically remove that item or at least mark it as "out of stock" until she is able to go in and delete the item. Neither of those things happen. Any tips or suggestions would be greatly appreciated.
