Now, shipping estimates for the iPhone X have improved to allow for free next-day delivery or same-day pickup, on the US Apple store website. The free next-day delivery applies to all in-stock products purchased before 3pm local time on Dec. 22.

Apple fans in the UK can also get next-business-day delivery on any in-stock iPhone ordered by 7 p.m. local time. The promotion is only happening in certain countries (sorry, Australia), but iPhone X shipping estimates have improved across the board to accommodate the holiday crush.
