I've no longer ship FedEx and wish companies that I buy from would stop using them.
I've had two bad experiences: (1) I sold and shipped a NAD M12 pre/DAC, FedEx lost the package. It was found and finally delivered two days late; (2) I sent a BHK preamp to PS Audio for repair. On the return trip, I received a FedEx "delivery conformation" email, but the preamp was not delivered to me. Instead, it was delivered to a house in my development. Luckily, the homeowner drove to my house and gave it to me.
I've had several other instances where I'd received a "delivery conformation" email, but no delivery. I complained to FedEx about it. The answer I received was (paraphrasing), "some drivers will do that if they can't get it delivered on time, but plan to deliver it the next day."
