In the US you can use stamps for Priority Mail packages; they're not just for letters! My dad does this when he sends packages because he can get (legitimate) bulk postage at odd denominations for less than face value. You can use more postage than will physically fit on the box; more postage can go into a shipping label pouch. I imagine the stamps get used up a lot faster when you're shipping packages with it. A tip to anyone wanting to get into this: legitimate bulk postage is sold by the pound!
