Clickfunnels Pricing is pretty straightforward...
There Are 2 Main Plans
The Standard Plan - $97/mo
The standard plan includes most of the functionality of clickfunnels, but with a restriction on how many visits you can have to your clickfunnels landing pages per month, and it also doesn't include some advanced functionality like email marketing or affiliate tracking.
The Etison Plan - $297/mo
The etison plan really includes everything - all of the clickfunnels features, and no limits on your monthly visitors or features.
I personally don't think you need the Etison plan until you're making some good money. Until then, the standard plan works just fine.
