Why not consult UPS tracking as an oracle for that case?

  Because UPS tracking is limited to determining whether UPS delivered a package. It can't say who the package was sent from, who it was delivered to, or what was inside.

    This is what Dr Sanchez on our team calls the "box of rocks" problem. You _could_ potentially use a lack of delivery to automatically refund the buyer or something but automatic payout to the vendor is harder.

    yes but this is also a problem in the real world right? I could order anything, sign the package once it arrived, and then complain that the box was empty. With or without a smart contract, it is hard/impossible to prove I'm lying or not. So I assume this case is mostly taken care of by insurance, not the platform fee? Or I guess that's what the platform fee is for?
