What happens if you purchase a product in FLUZ network, and everybody in the network receives cashback, but than you decide to return the product after a while. What happens to the cashback?
I guess the cash back will be voided and taken away, for example if you then withdraw the reward you received before it was voided FluzFluz would put your account in minus.
Would be that or I'd imagine you wont get the cash back until the return period is over, enforcing you to keep the product ( get cash back )
Or return it and lose the chance to get cash back

Either way I'm sure FLUZ have thought about this scenario
After reading all your comments, it looks like there are many ways to deal with this problem.
you wont get the cash back until the return period is over,
this makes a lot of sense to me. Even if they did like 1 month for all products, they are probably covered
