There is a lifetime offer on personal and family plans. You can use CMSAVE40 or BFSAVE40 and get additional 40% off. I just did couple of days ago and it works good on safari.
P.S. I am not affiliated with stacksocial or adguard in anyway. Just sharing the deal here i got it from the adguard reddit channel.
