I was trying to purchase “Commission Removal” for my apps.
There I saw an offer written " More apps less price ".
Sorry , I tried but I can’t figure it out how to get the offer .
I am very much interested to purchase 3 app’s commission removed.
So what will be the discounted price?

It automatically gives some discount on second or third purchase.
