Stupid question, I guess, but humor me:
My invites are 5.5" square. Everything I've read online, including the little disclaimer on the Wedding Paper Divas site where I ordered them, says that square = 20 cents more postage, even if it's under an ounce. However, I just went to 2 post offices, one local USPS branch and then the mail room at my building, and both of them weighed them and said nope, one 46 cent stamp is all you need. Then smiled patiently at me when I said "Really? Are you sure? For reals? Even though it's square?" etc. One lady even asked her supervisor.
Naturally I'm terrified to believe them, because oh my god, getting them all returned would be a nightmare. But that's three different people who deal with mail all day every day, so...Anybody else have this happen? Or did they take one look and say "yup, square, 66 cents, just like the Internet said!"
