I recently decided to add hot stone massage to my services. I was planning on charging $10 more for it as an add-on with my regular deep tissue massage. I also want to offer a seperate massage that would be a basic hot stone massage protocal. This would also be $10 more than my regular rate.Most of the regulars that I have are on my maintenance plans where I give them $5 to $10 off their massage depending on their regular frequency of massage.I was trying to decide if I would charge $10, $5 or add usage of hot stones on for free for the clients on the maintenance plans. For now I am giving them all a trial with the hot stones for free so they can experience them. It does take time to set-up and clean up, plus the added knowledge to use them. But, my maintenance plans are what keep my business going and I thought this would be a nice bonus for taking regular care of themselves. But, then again so is $5-$10 off the massage price that they already get!What do you all think?
