I've written about 1-800-FREE-411 and raved over their services before. For those of you out of the loop, it was one of the first free 411 services to crop up and it's still one of the best in my opinion. I probably use it a dozen times a month to look up a number I've long forgotten and the best part is that it's 100% free.
But to make matters even better, they're offering ato anywhere in the US on Valentine's Day this Saturday! Simply call 1-800-Free-411 come February 14th and there will be a prompt for the free call to any landline or mobile number here in the US of A. This is perfect for anybody living far away from friends and family without a long distance plan.
