How can I confirm my USPS and Paypal accounts are still linked? I did that several months ago. Today, after a long while I sold something on Ebay and I am using a padded flat rate envelope to ship. It says $7.10 as my cost. Is that a discount? In the past it would show some type of discount. I know the postal service has had an increase in their shipping prices, but want to make sure this is correct.
