Weirdest package delivery experience ever!?

[ripley802]

I must say I am quite confused on this. To elimate some of the mystery, the seller was me. Muddy won an auction from me a few days back. This was shipped USPS flat rate envelope, so the weight restriction would be 70lbs which it was not as it was one train. That said, I paid what eBay calculated, not something I came up with on my own to charge. If there are other USPS restrictions on using a flat rate envelope that would great to know if, but I am not aware of any that would result in this. Sorry for the hassle on this one Muddy, again, I am not sure what happen.
