I'm buying referrals to sign up under my link . When an offer is completed you get 1.00 credit to your account , i will pay 3$ for 1.00 credit and if you do more offers i will pay 3$ for 1.00 credit again. -The program is ZipNadaZilch , you will be able to earn 20$ per referral . -I pay by paypal , but the program have more options. -Credit card is needed but you won't be charged , there are free offers.
