Did the Post Office get rid of the Flat Rate Padded Envelopes? I've noticed in all of my listings that qualify to be shipped Priority Mail this option is not available through Ebay. Is this a new change in the postal system or another Ebay glitch? Thanks for any help provided.

Priority Mail Flat Rate Envelopes are available. Availability is based on what you show as dimensions in your listing (if dimensions are too large...then this option will NOT be available).
