why people still pay for Fillout
People still pay for Fillout because a basic form is trivial; people pay when the form feeds a dependable business workflow and never loses a response. The recurring cost buys spam control, email delivery, storage, exports, accessibility, conditional logic, and integrations, not just the visible interface. If none of that applies to you, any pick above saves $228 a year.
