Hi,
Thank you for reaching out.
Yes, the maximum usage limit option is for the overall usage limit of that specific discount rule. Is the number of users to which the discount applies. Something like early-bird discounts for the first 5 users or 10 users.
Are you would like to restrict the discount offer to one time per user?
It might be possible only when you are using WooCommerce coupon with our discount rules plugin.
Here are the step-by-step configuration to restrict the coupon usage to 1 time per user :
*Go to WooCommerce -> Coupons, and create your coupon code.
*Set the percentage discount to 0 value -> https://nimb.ws/Pe0dUC
*In Usage Limits, set the usage limit to 1 time per user -> https://nimb.ws/b82JME
*Then you can use this coupon code in Discount rules plugin and create your discount rules.
Please review this below guide to know how to activate discount rules using coupon codes:
