The Free Deals from Sharing add-on assigns a free deal to a customer whose friends have purchased the same deal or product through the customer’s unique referral link. This add-on simple to configure and it can be utilized on a per deal or product basis with different thresholds.
How is it free?
It depends on the payment processor you are using and if the payment has yet to be captured. For example, if your site uses PayPal and a tipping point is set for the deal then customers payments are authorized for later capturing. If a customer earned a free deal but his payment was not captured yet then his future captured payment would be modified and he would not be charged for that deal.
What happens if the payment was already captured?
Then the the equivalent to the final price is added as credit to the customer’s account balance on your site.
What about mixed payments?
If a payment is mixed, meaning if the purchase used multiple payment methods (e.g. credits and PayPal) then the free deal will be provided by an account balance adjustment, regardless if their full payment was not captured yet.
How are customers notified?
The add-on provides a new customizable notification that can be sent to customers every time they earn free deals.
