Digi-Key has what has to be a top contender for fastest order processing & shipment of any company that does e-commerce ever. No exaggeration, it's almost inconceivable how quickly they will pack up and ship out your order. Especially when considering most orders likely contain many different, intricately small parts each of varying quantities. For example, I've seen YouTube videos from AvE who lives in Canada, where he ordered a few ICs late-ish the previous night and UPS dropped them off at his door the next afternoon. And this isn't a one-off occasion, it's consistent.

McMaster-Carr might be comparable, though. At Georgia Tech, a MC order at like 9AM could realistically be received at like 1PM with the cheapest shipping option. Usually the slow link was GT Post Office.

But that's because MC has a warehouse really close to Atlanta.
