Does anyone know how often I can cash in my rewards?

Jana Kleven

I think it's once a day.   

21. You need to wait 24 hours between two cards

Nicole Comstock

It's every 24 hours.

Vicki Kieu

You can only cashed out once every 24 hours.

I always cash out at £5.  What is the limit as a matter of interest? 

There's a daily limit, so no more than one card per 24h 

I didn't know there's a limit.

That's a good question, I never tried to do more than once

As soon as you have enough coins.
