Check out CityPockets

I've been using various Groupon-ish web sites to great advantage. Whether it's Groupon itself, or LivingSocial, OpenTable and others, I send all their offers to an email folder and scan the 10-15 offers I get a day in one glance (2 seconds) to see if anything jumps out. I end up buying a coupon from one of them about once a month.

Along comes CityPockets. The site solves the problem of how to remember what coupons you have and especially reminds you to use them if you lose track of what you have. It actually can log into each of your groupon-ish accounts and grab whatever new coupons appears there and displays them in one unified list.

Free, useful and saves money too. I recommend CityPockets!
