Apple was previously offering free next-business-day delivery on all items purchased before that date, but to make sure presents arrive on time, that's been upgraded to free next-day delivery, which includes weekends.
For several years now, Apple has offered upgraded shipping options over the holidays to attract last minute shoppers who may not otherwise be able to get delivery of Apple products and accessories.
Apple is also offering an extended return policy, which will let customers return products purchased between November 14, 2018 and December 25, 2018 until January 8, 2019.
If you're still seeking gift ideas for the Apple fan in your life, we've created an extensive 2018 holiday gift guide with suggestions from MacRumors readers and editors.
Update: In Canada, Apple is also offering free delivery of in-stock items by December 24 if ordered by noon PST on December 19.
Update 2, 12/19: Apple is now offering free next-day delivery of an in-stock item ordered by December 22 at 11:00 a.m.
