From the Store description:
Groupon features deals on the best stuff to do, see, eat, and buy in more than 500 cities and eleven fiefdoms around the world. Our unbeatable deals typically weigh in at discounts of 50-90%, ensuring a level of access to your city that’ll put the mayor in a jealous rage. We handpick every deal to ensure that customers can confidently embrace salsa lessons, hot air balloon rides, and hand-tossed pizzas. Daily deals are signed, sealed and delivered to phones each morning.
Indeed. Nice prose, and of course salsa lessons and balloon rides are things without which I'd struggle to exist for another day. But you get the idea. And, come to think of it, those hand-tossed pizzas sound rather attractive!
Here's Groupon in action:
That car service offer looks rather good, let's drill down into the details... Note the limited time - Groupon is all about going back into the app every day to see what today's offers are!
Plenty of details on each offer, along with transparency on any conditions in the small print...
More offers from around my area, Groupon is unashamedly geocentric - which is good, as it saves on travelling, of course.
