I was saying just the other day that we were hopeful of seeing more Samsung Galaxy S III deals (perhaps encouraged by the iPhone 5's arrival), and here it is at Digital Rev for £370. Huzzah!
Available in Garnet Red or Pebble Blue at £370. Marble White, meanwhile, is £389.
Samsung Galaxy S III specs? Right here.
