While both parties started out with good reputations, if the seller doesn't come on here with a good case or take care of the problem, he is likely not leaving with a good reputation. Most likely scenario is that somewhere down the post office line , someone felt the tube and presumed it may have something of value. They are the thief, but the responsibility is the sellers. None of us jump for joy paying these claims, but it is the right thing to do. Seller decided to go cheap on the mailing and was lacking on the packaging, and it is a costly mistake. Seller should do the right thing now, or at least reply and get involved in a solution. The longer this thread continues the more damage that it will cause him. Make things right and he likely adds positive to his reputation. We all are great sellers when there are no problems.
PP really shouldn't be needed to resolve our problems
