Luckily not missing, but their delivery had the least amount of courtesy knocks (UPS, USPS, and especially DHL are much better about it, Amazon is second worst; I think it all depends on a driver), I try to avoid using it altogether, and when it's the only option - I ship package via FedEx for pick up to a local FedEx store (they keep it there for a few days).

Just heads up if you want to use the pick up: I had a medium size package (think a printer) sent to a UPS store, they charged me $10 for some bullshit hold fee, even though I picked it up hours after delivery was made. Could be anecdotal, but that surely caught me off guard.
