I have found some really great deals on Groupon. My favorite ones have been those to try new restaurants in the area that offer a 2 for 1 deal. My problem is that I will by the deal and then for some reason not be able to use it right away. The old adage "out of sight, out of mind" definitely applies to me. The good thing about Groupon is that even if I miss the expiration date of the deal, the money I spent buying the deal is still usable at that restaurant. If anything, I wish Groupon would send more reminders of when you are getting close to expiration dates.
