Why They Pay
Because of the Do Not Call laws, advertisers are now willing to pay people for their time and input. Look past the first pages of these sites and you will find lots of offers and surveys that are totally free—You just do them and you get paid. If the offer involves a trial period, just keep tract of the expiration date of the trial and contact information (phone number, etc.) so you can cancel before the trial period ends. The offers with trial periods have huge payouts.
