Apple has started selling refurbished Mac Studio in the United States, Canada, and select other European countries. You can save up to 15% by picking up a refurbished Mac Studio instead of purchasing a brand new unit.
Update: Apple has again updated its Certified Refurbished store with fresh refurb M1 Max Mac Studio units with one-day delivery for most locations. Stocks are unlikely to last for long, so if you find a configuration you want, pull the trigger on it.
