Hi! New to the Yoto world. I’m looking at the 2024 gen Yoto Mini. Is $59.99 a good deal or will Black Friday be better?
Also, I keep seeing things about referral. What is this?

Hi! This might be a dumb question so apologies in advance. I bought a Kenra demi permanent color and the lady that worked at cosmoprof handed me the developer. I got home and noticed the kenra developer is permanent. Is it ok to use those two together or do I need the demi permanent developer?
