Wealthy mainland Chinese looking to buy the new iPhone 6 on Friday could expect to pay an eye-watering $A2754 for the handsets in Hong Kong, after Apple's decision to delay the launch in China.
Hong Kong has long been a hub for resold and refurbished phones, and delighted vendors there were coping with a flood of pre-orders from the Apple-obsessed mainland.
The price, say HKsellers, is a bargain - the phones can then be resold on the mainland, where fans could pay up to 30,000 yuan ($A5390) for a new handset.
Apple last week unveiled the two latest models in its iPhone series, both of which boast a larger screen, to try to recapture its role as a technological trend-setter.
The phones will be made available in 10 countries - including Hong Kong - from September 19, but Apple has not yet stated when they will be available on the Chinese mainland, despite it being one of the US tech giant's largest markets.
Huge queues and frantic trading were seen outside Apple stores in Hong Kong on previous iPhone launches, with resellers buying units from hundreds of new iPhone owners to sell on later at inflated prices on the legal but unauthorised "grey market".
At Sin Tat Plaza, a bustling mall crammed with mobile phone stores in the city's Mongkok district, posters and replica models of both iPhone 6 models are already on display on virtually every corner.
"The demand in the mainland is bigger for the iPhone 6 compared to the iPhone 5s because there are bigger changes made to it," Arthur Chung, who runs a phone reseller shop at the three-storey shopping centre, told AFP.
Chung said he will order phones from the United States to match a pre-order for 300 units of the iPhone 6 made by a mainland customer .
The 128GB gold version of the larger iPhone 6 Plus could be resold for more than HK$20,000 ($A2843), Gary Yiu, the manager of the nearby iGeneration mobile phone store, told AFP.
Mainland China was among the first countries where the iPhone 5s was available for sale last year, and the then newly introduced gold iPhone 5s model was particularly popular. Apple also launched the colourful , cheaper plastic-case iPhone 5C, reportedly to satisfy demand in China.
"There have been reports saying that the iPhone 6 prices could reach over 20,000 yuan ($A3,593) to 30,000 yuan ($A5,390) in China, so the Hong Kong price isn't all that expensive," Yiu said.
In the US, the new iPhone 6 will start at the same price of existing iPhones at $199, while the iPhone 6 Plus will be at $299, with a two-year contract.
While in Australia, to buy the handset outright consumers will need to pay between $869 for the smaller basic model to the top-of-the-range larger model at $1249 at an Apple store or take a contract with one of the telcos and usually pay more for the handset in the end. Some eager buyers are willing to pay others to secure devices for them.
Apple's products are wildly popular in China, where a teenager sold his kidney and used the funds to buy an iPhone and iPad in an incident widely reported in 2012.
Apple said the devices would be available in at least 115 countries by the end of the year.
