I do not offer trial versions of the premium plugins, but I do have a 30 day money-back guarantee, allowing you to purchase any plugin edition free of risk. You have up to 30 days after purchasing to determine if the purchased plugin edition is right for you. If you determine it does not suit your needs, you may request a refund at any time within the first 30 days after purchase.
You may contact support at anytime if you have questions about a plugin.
If a plugin does not work out for you, simply contact us within the 30 days for a full refund. See our refund policy (EULA) here.
