Hello, So I ordered Priority Mail Flat Rate Envelopes (12.5x9.5) off
USPS but I keep getting the letter sized envelopes for some reason. Is
there any way to fix this?
Will sell an item that currently has the wrong weight( About 1-2 Ounches
off). Can I change the weight of the item during the process of buying
the postage from eBay after the item sells?
