With PayPal Pro, Stripe, and Authorize.Net (i.e., with any of these payment gateways that work with s2Member Pro-Forms), you can build a configurable list of Coupon Codes that provide a flat-rate discount. Or, a percentage-based discount; up to and including 100% of the transaction amount (i.e., a 100% free checkout experience is possible). Coupons can be limited in scope too. Such as limiting the discount to the first/initial payment only, or to regular recurring payments only. It's also possible to limit Coupon Codes to specific Pro-Form instances, to specific customers, to specific dates, and even put a limit on the maximum number of times that a specific Coupon Code can be used collectively. It's also possible to integrate s2Member's Coupon Code functionality with affiliate platforms. Affiliates can be identified through promotions that use affiliate-specific Coupon Codes, which your Pro-Forms will graciously accept. Tracking the Use of Promotional Coupon Codes
