How do I reuse a postage stamp?
<|assistant|>
You can reuse a postage stamp by attaching it to a newly printed envelope or letter. However, due to changes in the weight and size of letters over time, there is no guarantee that the postage stamp will actually be accepted for postage. It is generally best to use postage stamps to mail items that weigh less than 3 ounces and meet the USPS' standards for size.
