Clearly, Amazon isn't content with a small, AmazonFresh-style delivery service. The company is expanding its UK operations today with Amazon Pantry, a new way to order "everyday essentials." It's exclusive to Prime members and offers next-day delivery for more than 4,000 products, including basic food, drink, beauty products and cleaning supplies. The service isn't meant for fresh produce -- you can't order a pack of bacon or some bananas -- but rather cupboard regulars like cereal and tinned soup. As you pick items from Amazon's store, you'll see a "Pantry box" beginning to fill. The exact dimensions aren't clear (they're probably flexible) but Amazon says each one can hold 20kg. The first box in your order costs £2.99 to deliver, followed by 99 pence for each additional box. These prices are on top of your Prime membership and what you'll pay for each individual item.
