If you were planning to purchase AirPods as a last-minute holiday gift, it may be challenging to find a pair in time for Christmas.

Apple's wireless earphones are currently estimated for delivery in early January if ordered today from Apple's online store in the United States, Australia, Canada, France, Germany, Italy, Spain, United Kingdom, and several other countries.

AirPods are also currently out of stock at most of Apple's retail stores around the world, and at authorized resellers such as Best Buy, Macy's, Target, Walmart, and Verizon in the United States. Bottom line: they're hard to find anywhere.

At $159, AirPods are a more affordable gift idea than many Apple products, which may be causing stronger demand than Apple can keep up with.

If you are still hunting for AirPods, there may be one option. AT&T appears to have stock on its website, but you may have to pay an extra $14.95 for express delivery within 2-3 business days, and there is no guarantee they'll arrive before Christmas.

Other gifts available by Christmas for under $200, and that an Apple fan is likely to appreciate, include the Apple TV 4K, BeatsX, an official Apple-branded iPhone case, Apple Watch bands, or simply an Apple Store or Apple Music gift card.

Apple's online store is now offering free next-day delivery for all in-stock items ordered by 3 p.m. local time on December 22 in the United States.
