Groupon London are giving away £50 worth of credit to a winner with their new Instagram launch. All you need to do is upload an image to your personal Instagram account using the #grouponuk hashtag. Then post a comment to the Groupon London Facebook page, see here, with your username.
Groupon London are really looking for anything Groupon related, so perhaps a lunch you picked up from Groupon or a shot of you relaxing on a Groupon Getaway.
