Last year I sold my last Nitro 4 stroke engine ( OS 70 ) sold it to a guy in Minnesota, it went from Sac to LA, then to Minnesota, sat at their distribution center for days, then it was out for delivery, then it showed delivered, then on the same day it showed out for delivery again, at the end of the day it showed delivered to Amazon warehouse where it disappeared.

I filled a complaint, I got an email saying that my complaint has been resolved and that they will reimburse me for my item, I had to return the money to the buyer.

Never saw a dime from USPS, they quit looking for my box and decided just pay for it and close the case.
