I recently found that USPS makes no guarantee of delivery. I paid a premium price for Priority Mail to send some documents to my attorney, about 35 miles away. Should have been overnight, or in this case, mailed on Saturday, promised delivery for Monday. It got there Wednesday afternoon at 3:39. When I went to the Post Office to complain and ask if they offered any refund, they said they didn't, and there was no guarantee but I could have paid the $25 fee to have the letter delivered on time. On the other hand, I sent your shirts the cheapest I could, cost me less, and your shirts got to you in 2 or 3 days.
I have more shirts to pick up, today, including your Member shirt.
