I got an email from USPS.com today asking me to pay $6.05. No biggie, but, the shipping label was from February, paid for via Paypal, shipped to a buyer in PA. The notice stated that the label has been reused in August, and the package was shipped to OH???? I am suspecting that the buyer reused the label barcode (cut/scan and paste) and stick it on his package to OH. Lucky me I've all the records and can do an appeal. My suggestion is to print out everything, even D/C, and file them. Do not throw them away!
