I seriously question the loyalty of new Groupon customers. Typically they sign up because of one deal. They might even buy the deal. Then Groupon proceeds to spam them every day with deals they aren't remotely interested in, at locations far from their home. Unsubscribe.

This. The problem is that Groupon's variety of merchants is very low - I suspect because it's only worthwhile to merchants with an incredibly wide profit margin (e.g., spas or other services that have low variable costs).

I unsubscribed after I kept getting deals I had zero interest in. It seems once in a while they'll get a "big deal" from a well-known merchant to get people back in - but 99% of the deals I've seen from Groupon are utterly useless.
