Apple's doing something for Black Friday — we just don't know exactly what it is

Apple is promoting a special one-day shopping event on Black Friday — but so far, the details are a mystery.

The company has posted a holiday gift guide, touting a one-day shopping event happening this Friday. But so far, the only promotions listed are free two-day delivery on in-stock items ordered by 5 p.m., and extended shopping hours.

There may be more to come, as Apple urges users to "come back this Friday to check everyone off your list." But for now, the page lists a gift guide of Apple's regularly priced items. CNBC has reached out to Apple for more details but has not heard back.

Still, any promotion would be a departure for the tech giant, which holds few sales. It has, in the past, offered bundled gift cards, but has more or less stayed away from the holiday rush in recent years.

Meanwhile, retailers have done their own discounts and promotions. This year, Target is offering 25 percent off Apple TV models, 20 percent off iPods, and sales on Beats headphones and iPads. Best Buy is offering $125 off iPads and $50 off Apple Watch Series 1, as well as offers on Macs.

Apple has promised investors that it will return to revenue growth, after reporting three straight quarters of iPhone sales that were lower year over year. Demand for the new iPhone 7 was stoked in part by aggressive promotions from wireless carriers this fall.
