Someone please explain...

Now, can someone please explain to me why we just received a box full of our "save the dates" in the mail returned to us? We mailed these out SEVERAL days ago from a post office where the postal worker informed us that the stamps she put on each envelope were more than enough to pay for the postage of each individual piece of mail. Then, we get this box of our "save the dates" returned to us, and a note stating we need to add a dollar seventy nine or so more PER ENVELOPE! Has anyone ever had this trouble before? Isn't the post office a federal quote unquote company that should be regulated for each state and each city and county? That is all. thank you.

Brace yourselves, fools at the local Post Office, for the wrath that is Eddie going postal on your ass tomorrow.

And...AND they could work together enough to find a box to put these in, but not come to an agreement on how much these identical envelopes are costing us to mail.
