Instead of taking the UK's supermarkets head-on, Amazon has decided to ally with them in order to boost the popularity of its Pantry service. The site, launched in November last year, allows Prime subscribers to remotely order more than 4,000 products with next-day delivery. Now, it's announced a deal with Morrisons -- a heavyweight supermarket in the UK -- that will add "hundreds" of new products to its platform. They'll also be available through Prime Now, a one-hour delivery service that's available in a smattering of cities. Morrisons says the new additions will appear on Amazon "in the coming months" and include fresh and frozen goods.
