An online cashback offer, commonly known as an e-CDI, is an electronic system that allows consumers to receive a refund on their purchases. Unlike traditional cashback offers, e-CDIs involve communication exclusively online, whether through the brand’s website, email, dedicated platforms, or banner ads.

To take advantage of this offer, consumers must create an online account, either before or after their purchase, and before submitting the required proof of purchase. This simplified process offers greater flexibility and better control of the offer for the advertiser, while also adding a relational dimension to their marketing campaign.
