Here is one I got today, mailed from 87023 at 10:02 AM 3-30-12 delivery attempt to 85009 was made 3-31-12 9:50 AM as noted above label, with a note on the right of the label "closed".Delivered today 4-2-12 at 11:45 AM, the sender paid $18.95 for the flat rate express rate, 3 days for delivery, inside the flat rate envelope was a business envelope that could have accomplished the same for .45 cents, had it been mailed off first class. And as you can see, no cancellation of the stamps and a miracle of sorts the stamps did not get pen stroked or the marker. So I have $18.95 in postage I can use or just leave the cover as is as the cover is postally used.
