Gaming consoles, including the Xbox One and Playstation 4, and low-cost tablets such as the Tesco Hudl and Aldi Medion Lifetab are expected to top many people's Christmas lists this year, but many suppliers have reported that their devices are already unavailable.
Both the Xbox One and the Playstation 4 have sold out in the UK, with Amazon and other major suppliers now warning that any orders will not be fulfilled until after December 25.
Microsoft announced this week that it has sold two million Xbox One consoles in the space of 18 days since its launch on November 20. "Demand is exceeding supply in our 13 launch markets and Xbox One is sold out at most retailers," said Yusuf Mehdi, corporate vice president of strategy and marketing at Xbox.
Meanwhile, Aldi's low-cost tablet, the Medion Lifetab that went on sale at the supermarket chain over the weekend, has already sold out in all stores, and Tesco's Hudl tablet has sold out twice in the run up to Christmas.
Treeva Fenwick, head of consumer and broadcast media at Tesco, said that the Hudl is the fastest-selling tablet that Tesco has ever sold, and the company is working with its suppliers to get more in to meet demand.
The most popular gadget to appear on all Christmas gift predictions that is still widely available is Apple's iPad and iPad Mini range. Google's Nexus 7 tablet is also still available from the company's own Play store.
Many of the sold-out devices are available at elevated prices via online marketplaces. The Hudl tablet, which would normally cost £119 from Tesco, is attracting bids of up to £145 on eBay, and there are some reports of eager gamers forking out almost double the recommended retail price to get their hands on a PS4 before Christmas.
The news seems to confirm predictions that technology and gadgets will feature high up on many people's Christmas lists this year. A report by uSwitch last month revealed that parents will collectively be splashing out over £3 billion on tech gifts for their kids, spending an average of £243 each.
