Is using USPS priority mail united states postal service boxes more expensive than using a cardboard box?
Do the USPS priority mail boxes have a tax on them or is it just the pounds of the items that really matter not the type of box?

It depends on the weight, I just shipped a 3 pound item for $7.68 with a box slightly bigger than a Medium flat rate box. The medium box would have cost me a little over $11. Always use your own packaging unless the item is very heavy, as flat rate boxes can ship up to 70lbs without the price changing.Source(s): Personal experience

If your items weighs more than two pounds, it is probably cheaper to use the Priority box, which is not charged by weight. Any other box is charged by weight and size. Only if you are mailing books can you get a better rate.Source(s): Retired USPS

It depends on the weight of the item. Sometimes the flat rate boxes are cheaper and sometimes your own box will be cheaper. You can use the postage calculator on the USPS website to compare the prices based on the size and weight of what you're shipping.

the boxes are free there no charge for the boxes
but you will have to pay the priory mail rate to send it
you cant send it another way [ie media mail, first class ec]
like you could with cardboard box
