Would you like to try Gravity Forms before you buy it? You can use the following link to spin up a demo site where you can test Gravity Forms and all the official add-ons for several days: https://www.gravityforms.com/demo/
Please note: the mail() function on the demo sites is disabled. You will need to use an SMTP plugin configured with your own SMTP settings in order to send the notification mail. Take a look at the alert in the blue box on the demo page for some suggestions on plugins you can use for that.
Also, did you know we have a 30 day refund policy? http://www.gravityforms.com/refund-policy/ You can purchase Gravity Forms to install on your own site, and if things do not work out, or you’re just not happy with Gravity Forms, go ahead and request a refund here: https://www.gravityforms.com/refund-request/
Any questions about the demo site? Please create a new topic here and we’ll be happy to help.
