+ * Gravity Perks // Limit Submissions // Dynamically Set Limit by User WooCommerce Product Purchase Count
+ * https://gravitywiz.com/documentaiton/gravity-forms-limit-submissions/
+ *
+ * Dynamically set the limit by how many times the current user has purchased a specific WooCommerce product.
+ * This is useful when a user must complete a form once each time they purchase the product.
+ * Note: This requires users to be logged in, so does not work for guest purchases.
+ *
+ * Instructions:
+ *
+ * 1. Install the snippet.
+ *    https://gravitywiz.com/documentation/managing-snippets/
+ *
+ * 2. Configure the snippet based on inline instructions.
