Why no media mail or Parcel Post as an option?
Media mail from what I have experenced as a buyer is slow and according to what my post office told me is not allowed to be used for sending postcards. I also have bought things and paid for Parcel post. While it’s cheaper than priority, the big drawback is the service is very slow and the difference of saving a quarter to a buck isn’t really worth the worry about where things are. Priority Mail comes in with three to four days after being posted for the most part. At the latest, I’ve seen a five to six day turn around.
