Apple Will Prohibit Walk-In Purchases of iPhone 6S in Four States Without Sales Tax

Apple's newest iPhone goes on sale Friday at 8 a.m. ET. But you might not be able to just walk into a store and purchase the iPhone 6S or iPhone 6S Plus if you live in one of four states.

The technology company is not planning to allow walk-in purchases in states without sales tax, according to a footnote in a recent press release from the company. That means people in Alaska, Delaware, New Hampshire and Oregon won't be able to get their hands on the latest gadgets unless they have made a preorder reservation.

"IPhone is available by reservation only in China, Hong Kong, Japan and U.S. stores in tax-free states," the company wrote in a release ahead of the sale. Those reservations, however, aren't being accepted again until September 26, a day after the official debut.

Apple didn't immediately respond to Newsweek's request for comment. It was unclear if this was a new policy.

Montana is the fifth state without sales tax, but an Apple retail store isn't located within its boundaries.

The new phones come in two sizes, the regular 6S and the 6S Plus. They will be available in space gray, gold, silver and rose gold. The phone model is redesigned with 3D Touch technology, which allows for a more delicate user experience. Its upgraded camera includes the Live Photo feature, which essentially is a GIF-generating system.

The iPhone 6S, announced at Apple's annual September event, will start at $199. The 6S Plus will start at $299. Preorders began on September 12.

As always, the debut of the new iPhone is expected to cause notoriously long lines outside of retail stores across the country. The company encourages walk-in customers to arrive early.

Local leaders and the U.S. Postal Service have warned that Pope Francis's visit to Washington, D.C., New York City and Philadelphia this week will bring delays. Expected postponements for shipping companies along the East Coast suggest that people might not get their new iPhones on time.
