Having just read the link this part is bothering me-
The Postal Service also is seeking approval from the Postal Regulatory Commission to automatically include insurance — at no additional charge — with most Priority Mail pieces. Customers will receive $50 or $100 of insurance coverage, depending on the postage payment method used.
Depending on the postage payment method? I assume that means they short you on the included postage if you use stamps? Or should I be getting something else out of that?
