I think I made a big mistake. I had taken my wedding invitations to the post office and gotten the postage accurate. We mailed a few out and they arrived just fine. The rest needed to go out today, so I went over to the post office. I got there about 15 minutes after they closed, so I decided to drop them in the box. Well, after inserting all 100+ invitations, I see this sign that says if your mail is dropped in the box, and it's over 13 ounces, then your mail will be returned back to the sender - some security thing. I'm pretty sure my invites are over 13 ounces since the postage was so much. Has anyone else had this happen? Am I going to get all of my invites back? I think I'll go to the post office first thing in the morning and see if I can just retrieve them and have the counter process them. I thought this whole hand-canceling thing was optional!
