I finished up my invites last night and asked my fiancé to help. I originally put stamps on all the invites myself a few weeks ago, but ran out of stamps because we added some last minute guests. I asked my fiancé to put the stamps on the envelopes. My envelopes needed 70 cent stamps. I instructed my fiancé to put the 70 cent stamps on the mailing envelopes and the 40 cent stamps on the returns. He completed the envelopes, I stuffed and sealed them, and put them in the mail this morning.
I came home from work today and my fiancé said he I had a confession. I asked what and he said that he thinks he mixed up the stamps on some of the envelopes. At one point during the process, he took a phone call and then came back. When he came back, he said he might have switched the stamps and realized it this morning after I mailed them.
I'm stressed out now. What's the worst case scenario here? I checked each envelope to make sure it was sealed all the way. Now, I wish I checked the postage. This is only 20 invites out of close to 100 we sent.
