If you use Peoplefinders you will receive unrelenting calls to the number you give to sign up for BudgetSavers for a $29.95/month service offering coupons and savings that are not worth it.
They are persistent and will not allow you to say no. And if you (unwillingly) sign-up (for $14) with the hopes of getting $100 worth of free gasoline, you will find that the time it takes you to receive the $100 coupon will mean you will be charged for the 1st month of the $29.95 service.
So you will spend $0.95 + $14 +$29.95 to get a phone number. Don't do it. Call Information instead.
