Eagle-eyed customers browsing the Fly Buys rewards catalogue this weekend were seemingly able to buy the latest iPhone for just $140.
Apple's iPhone 11 Pro Max retails from $2149, but Kiwis received an unexpected discount when buying the phone through the loyalty scheme.
The phone was listed on the Fly Buys website for 805 points - the equivalent of about $140.66.
Stuff reports one man ordered eight phones for $1188.59, which is less than the RRP of one iPhone 11 Pro Max.
Another man who bought one of the hugely-discounted Pro Max phones said the transaction had been charged to his credit card but the deducted Fly Buys points had been reinstated.
A Fly Buys spokesperson told Newshub the company is aware of the pricing error.
"We are aware that a 512GB Apple iPhone 11 Pro Max was displayed on the Fly Buys website over the weekend with the incorrect number of points required for redemption. This was an error and we apologise to our members for any inconvenience this caused.
"We will be refunding any points and/ or money that our affected members spent on this product and we will be contacting these members directly today."
The Fly Buys website was offline overnight on Sunday - reportedly due to hopeful customers flooding the site in the hopes of snapping up a cheap iPhone - but is now back up and running.
The Pro Max appears to have been removed from the Fly Buys website, although the Pro is still available in three different storage sizes. The most expensive model - the iPhone 11 Pro 512GB - is listed for 16,735 points or about $2860.
The new iPhone models - including the iPhone 11, iPhone 11 Pro and iPhone 11 Pro Max - have been available in New Zealand stores since September 20.
