I have been very overloaded with emails, so I have been unsubscribing from as many as I can. Today, though, I heard about YipIt. As a general rule, I used Groupon, but there are a lot of other social couponing services out there. I have neither the time nor the desire to go through all of them to see what I might like.
What I like about YipIt is that it aggregates 145 such sites and lets me choose what types of coupons will come through. I never have to sort through gardening, tanning or automotive coupons again. Hurrah!
