Unique Mailing Situation. What Would You Do?

Jim, did you try to call the UPS Store that came up when you Googled the address? Maybe they will know the guy by name if you call them. Maybe they could tell you if he has a PO box there or regularly has stuff sent to them. It's strange that he hasn't reached out about the deal.
Didn't the cat PayPal him some cash for return shipping? It's definitely an oddity most car guys want their parts before they can get them!
