The lifetime membership option is one that may be removed at any time. We removed it for over a year and then brought it back due to popular demand. Once demand starts dying down, we'll probably remove it again.
This is what I thought.
It comes, it goes, it comes it goes.
There is never a time frame of when it will be removed, when it will come back. It is just buy right now when you can and got the chance and do not worry then
You are set for life
