Ask How do you set up a lifetime access membership?

[SuperAffiliateX]

I want to offer lifetime access to my membership site but I don't know how to set it up. Do I just charge a one-time fee, or should I add extra perks? How do I make sure it's sustainable long-term? I don't want to lose money by pricing it too low. Should I limit what lifetime members get compared to monthly subscribers? I also want to make the offer attractive without hurting future sales. If you've set up a lifetime membership before, what's the best way to do it?
