I posted this on the invites and paper board but thought I could get more help here.
My mom asked that I send some of my out of town family members (8 people) their invitations now because they need to make travel arrangements. Most of the rest of our guests are local so I will be sending their invitations in late May.
I brought a completed invitation to the post office to get it weighed. It was really busy that day and the line was long so one of the workers asked people in line what they needed help with before they reached the postal worker behind the counter. He got to me and I said I needed my invitation weighed to determine whether it needed more than a regular 45 cent stamp. He weighed it (somewhere where I couldn't see him) and said I'd be fine with a 45 cent stamp (I forgot to ask the weight).
I went to a second post office and they said my invitation weighed 1.1 ounces and that I'd need a 65 cent stamp. I asked him to re-weigh it. He cleared the scale to 0.0 and re-weighed it with the same results.
I am going to mail my invitations from a third post office tomorrow. If they weigh above 1 ounce, I'll use 65 cent stamps. BUT, if they weigh less than 1 ounce, should I assume that the second post office was wrong and use a 45 cent stamp? I don't have many extra invitations (trying to save money) so it's important that the postage I use is correct.
Which post office would you trust?
