I understand that since they pay for it, they wouldn't want the package to be used solely for a cheaper class mail as they would be losing money. But they expect most people to use it once, and then it gets tossed, no? So what harm comes from it being re-used instead of tossed or before it gets recycled? I wish more people were aware of this and would make a stink about it. It is wasteful and the USPS should be ashamed of themselves.
OK, but how can they prove the bag was used for priority mail before? What's to keep an unscrupulous person from writing a phony address on the envelope, turning it inside out, and sending something out non-priority? Only by not allowing the bags to be re-used for anything but Priority Mail can they prevent that from happening.
Bottom line: The bags are property of USPS, they can decide how they are used. If the practice bothers you, then don't use the free bags.
