Case Packs
A case-pack is a group of the same product packaged together in a single box or container. For example, if you're selling phone chargers, a case-pack might contain 50 individual chargers. This packing type simplifies the shipping process by allowing you to ship multiple units of the same product to a single Amazon fulfillment center without extra placement fees.
Amazon has specific guidelines for case-packs, so we recommend checking out this article if you're new to listing them: Case-packed
When listing in Boxem, Amazon will assign units of the same ASIN to the same Pack Groups in Step 2. From there, you can assign the units to boxes to match the quantity of your case-packs.
