Safelists (& Other Traffic Sources):

Safelists are sites where you can advertise your offers to other members, in exchange for receiving their offers.
You'll need two email addresses: one for contact emails from admin, and the other to receive ads from members.
(NOTE: Most sites will offer you some free mailing credits when you join to get you started).
