We recently told you about Apple’s free shipping holiday promotion for its online store. Any order placed through December 22nd will be shipped for free, including orders that are under $50.

Apple has added another perk to its promotion by offering 2-3 business day delivery for free. This means that online orders will be shipped much faster throughout the holidays.

Standard shipping can take up to 5 days, and with Christmas less than two weeks away, it’s getting too late for last-minute gift orders. While Apple’s free shipping deadline has not changed, customers can receive their orders much faster through next Thursday.

As MacRumors notes, you need to place your orders by December 19th if you want them to arrive before Christmas. Certain products have their own free shipping deadlines, as built-to-order Macs are not included as of tomorrow. The window for free shipping on the iPhone 4S has already passed (shipping is now 1-2 weeks), but that’s to be expected considering the high demand.

Apple’s holiday shipping page has all of the deadline information and other details.

You can always pay next-day shipping if you really need to get that iPod touch soon, but we would recommend actually visiting a retail location if you’re that desperate.
