I’m trying to setup a way to keep track of customers sales, and when one buys 10 products like 10 big pizzas, they win another for free.
But i have no idea how to do this. I’v searched i little bit for it on the forums, and i found this: SambaPOS Loyalty Card Features
its looks the right way to it, but not exactly what i need.
can anyone please give me some direction on my goal ?
