How can I get packaging done?

Packaging can be done by you, by your prep/inspect center or by your fulfillment center.  When you begin to automate your supply chain the prep/inspect center prepares your products for the fulfillment center to receive your products and then the fulfillment center prepares your products to go to the customer. In the beginning, you can do it yourself and Amazon has guidelines as to how they want to receive your products to their warehouses on the FBA website.
