We are having a destination wedding with a small party back home. We ordered two sets of save the dates with envelopes. When we received our save the dates, only one of our cards was there. The other belonged to some other couple. HUGE MISTAKE.
We complained and they sent us the save the dates that we were missing.
Now that we had both sets, we went to stuff our envelopes with both. We were sent the correct number of envelopes (55). We had ordered 55 of each set of save the dates. Now when we went to fill them, we realized they had sent us 48 of one card and 60 of the other card. WTF. I will definitely not be using them for our invitations.
