CashBeck services are quite popular among users of both online stores and standard offline stores. I think that this direction has a great future. Project PARQ has chosen a rather promising direction for its development.
I always say that such innovations have a very positive effect on us and on society in general. Because it greatly simplifies our life and makes it possible to save on purchases if there is not enough money.
Of course, such platforms are used by many people, the most important thing is to find a good platform with favorable conditions.
