I`m thinking you only want to purchase what you need for an order, because you really don`t have the room for all the inventory, or you don`t want to get stuck with unwanted items? Am I right? When I receive an order for a food gift basket, that`s when I go out and purchase the items. I do this because I don`t like to have food sitting around and possibly expire. But for most of my items I do keep a few of each in stock, so I can put together a basket at a moments notice. So what you need to consider, is, when someone orders a product, and you order it from your supplier, will you have enough time to get the product and ship it to your customer?
