A lot of people ask me where I find deals. Most of the time it's from other blogs. (Check out my blog roll to see my favorites.) Following them on Twitter saves TONS of time! I don't know why it took me so long to sign up. I guess I didn't see it's coupon value. :) Twitter also helps with time sensitive deals....and there's a lot of those!
So if you don't need/want one to tell all your friends what your ironing at the moment, you could use it to stay current on all the ways to save money.
