Too funny you mention this MayFlower because I was told this exact same thing (OK it was Biscuit) so I am totally sold on USPS right? Well, I went to the Post Office today to mail a package with 2 steelbooks to the UK and I am very proud of my packaging skills. Guess what? That 40-60 years old Postal Worker took the package with the customs declaration and tossed it towards the back window, aiming to get it through the curtain opening. Only thing is he overestimated the weight on the package and threw it too hard and it went high and hit the top wall of the opening. I had never laughed so hard and so much in my entire life looking at the face of that older gentleman. He looked like he was stuck in the middle of long push while sitting on the toilet, cringing and turning red. Priceless.

No worries the box is fine thanks to my fine packaging skills
