Planning promotional offer - polybag items as a set?
I’m preparing a shipment of inventory to Amazon FBA . I am planning to offer a promotional giveaway product with every sale. Do I need to polybag the items as a set or can I leave them separate?
Let's say the items are cellphone cases and the giveaway items are screen protectors. I have nearly 400 items so I am concerned that if I keep items in their own polybag, they may go to different FBA warehouses . What should I do? - bag them as a set? (one cellphone case with one screen Protector)
