Recently I signed up for Groupon to see what all the fuss was about. Even though they don’t offer services to any cities on this side of the world yet, I can see that they’ve got a great business going on. Since signing up I’ve been receiving daily emails from them but nothing relevant to me being outside the US. So I finally got around to unsubscribing today and the page I landed on once I’d unsubscribed let me punish someone! They have an interactive tool that lets you take your revenge on the guy who thought it would be a good idea to send you the emails. It’s not real of course, but it’s fun, memorable and lets you know that they’re on your side. Check it out for yourself without having to subscribe.
