Ask What’s a Low-Cost Sales Funnel for a Membership Site?

[SuperAffiliateX]

I want to set up a sales funnel for my membership site. I don't have a big budget. I see expensive tools like ClickFunnels, but I need something affordable. Can I build a funnel using free or low-cost options? I also want it to be easy to set up and manage. It should help me get more signups without spending too much.

What is the cheapest way to create a sales funnel for a membership site?
