ES uses “next order cashback coupons” campaigns to drive new unspected sales. It includes a simple web app where store owners can create and configure campaigns, register new sales, and issue/manage coupons. Coupons are delivered via SMS using AWS SNS.
The ElasticSale is built with Python/Django and ready to deployed on Platform.sh (there is a YAML file).
