I had reported this "known issue" to ebay 90 days ago....they admitted that it is in their bug reports but the issue is still not fixed.
I am currently listing auctions that ship in a USPS Flat Rate Regional A box. If I print a label individually it will pick up that Regional A box.
If I bulk print labels.....the import changes the freight from USPS Regional A to Priority mail.
Ebay please fix this.....it's driving me nuts!
