On the evening of October 16, Apple's inaugural foldable iPhone Duo hit the pre-sale market, igniting a surge of fervor among consumers. The sales platform was inundated with such an overwhelming volume of orders that it experienced a temporary crash. The first batch of in-stock items was rapidly depleted, with shipping dates for subsequent orders being rescheduled to January of the following year. This disparity between supply and demand has spurred substantial price hikes in the secondary market. On the Dewu platform alone, over 700 units of this model have already changed hands, with the 256G variant fetching prices as high as 21,900 yuan. Notably, the black 256G version soared to an astonishing 31,999 yuan, marking a staggering 16,000 yuan premium over its official retail price. On alternative second-hand platforms, the average premium hovers between 6,000 and 10,000 yuan. Scalpers have divulged that to guarantee acquisition of the first batch of in-stock items by October 23, a minimum markup of 6,000 yuan is imperative. Certain merchants harbor the belief that the current market dynamics are unpredictable, with prices subject to daily fluctuations; nonetheless, they foresee this model emerging as the one with the most significant premium.
