Instructions

Go to the eBay supplies page of the US Postal website.

Select the boxes that you want. It is a good idea to keep several sized boxes on hand unless you always sell the same item on eBay. You will probably also want to order both standard priority shipping and flat rate boxes. Heavier items can often be shipped cheaper using a flat rate box.

Determine the number of each size box that you want to order. Most are offered in either ten or twenty-five.
