Once you have completed configuring your account, you will be able to ship newly eligible units without individual FBA labels in 24 hours. After you have chosen the Stickerless, Commingled Inventory option, newly eligible items or new product listings that you create in eligible categories will be automatically eligible for shipment to Amazon without individual FBA labels. If you want stickerless commingling to apply to your existing inventory, you have two options. Items in these categories must be sold through with existing labels or removed and inbounded as new items and listings.
