… The shipping API team’s bug bounty, then? Though there’s probably a government intermediary on the planet who’d like to collect it for you; I didn’t expect small claims court to offer more than a keyhole to agency negotiations (iff reordering to a different location puts it where a Small Claims Court has jurisdiction), but I haven’t fingered the valuation administrator or irregular trade transmogrifier here.
At that point I feel silly not mentioning asking the shipper to collect their $300 adequately.
