This is sort of IT related.

Amazon has launched a UK grocery web site, taking on the established supermarket giants such as Tesco, Wal-Mart's Asda, Waitrose's Ocado and Sainsbury's.

Not only that, you can buy beer on the site. Perhaps the ultimate in laziness for the home-worker that cannot even be bothered to pop out to the local off-license anymore!

While Amazon only has a limited range of groceries on their website at the moment, hopefully this will increase substantially in the near future and offer some credible competition for the established supermarkets. Amazon need to offer better shipping options and lower prices for it to succeed IMO.
