I will start
Bronze/silver/gold package %30 OFF
Platinum/ Diamond/APi's %40 OFF
It is for a one time invoice.
So if you do a yearly it is off the whole year. If you do 1 month then it discounts 1 month only..
So I would suggest a year if you do it. If yearly it is 10% OFF already.
55% OFF Any plan. %75 OFF for the first hour of sale and then a few other hours during the course of the weekend.
Now if I could get ahrefs for %50 OFF I would be happy
