Game over: why Santa may struggle to bring you that PS5, Xbox or iPad

Some of the most popular Christmas presents are being sold online with mark-ups of more than 70% after selling out in major high street stores because of the global shortage of microchips. Supply-chain bottlenecks and the computer-chip shortages are affecting availability of some of the most sought-after gifts, from games consoles to Dyson products. Shoppers were warned last week of a delay of at least one month for some of the most popular iPad models. Games consoles have been in limited supply for most of the pandemic, and companies are struggling to cope with the surge in demand for Christmas. Customers have attacked "scalpers" online for buying stock and pushing up prices.
