ClickFunnels is an excellent tool for building everything from a single web page to entire sales funnels, complete with upsells, downsells, order bumps, and one time offers (OTO’s).
ClickFunnels is a Saas (Software as a Service), and it is purchased via a monthly subscription. At this present time, and at every time since its launch, there has not been a way to get a Lifetime ClickFunnels Account for a one-time price.
There are a few ways to get deal when you sign up, and Funnel Builder Secrets (direct link) is the overall best offer that they have. You get tons of quality training and a discount on your ClickFunnels account for the first several months.
