Bought USPS label before cancelling order


I had these open orders in my queue and I went to purchase the USPS label before looking at what they wanted. I realized that I did not have a certain part to that order, so I messaged the buyer and cancelled their order. After cancelling, I did not see a section where to get a refund for the labels that I bought on Amazon. Are these automatically refunded when I cancel the order, or do I have to request Amazon or USPS to get a refund?


find the order, there is a place to cancel the label (for a limited time). It then takes a couple weeks to get the credit assuming it doesn’t get used. If you wait too long, then you are just out.
