Ask What are the pros and cons of a lifetime membership?

[SuperAffiliateX]

I've seen some sites offer lifetime memberships instead of monthly or yearly plans. It sounds like a great deal for members, but I'm not sure how it affects the business long term. Does it bring in enough revenue? Could it lead to problems later? I also wonder if it keeps members engaged or if they lose interest over time.
