Sociaby provides a small widget that offers users the option to share their purchase in exchange for a coupon code. Our network tracks how valuable a tweet or share from a given user can be and allows you to adjust your discount offer accordingly. Not only do you get social mentions at a much higher rate than passive share buttons, but you also prevent abandonment and save money on affiliate commissions by keeping users in your checkout flow rather than Googling for coupons. An account with Sociaby is required to use this extension. You can get more information and sign up for our free beta or a free trial at sociaby.com.
