Using this module, you can make your store's coupons available to certain customers.
After installing the module, the list of customer groups will be added to the coupon form, and you can select the customer group you want so that the coupon is only available for the customers of that group.

Also, this module allows you to choose the maximum amount of discount for your store coupons.
When you set the maximum discount for a coupon, the discount amount of the coupon in the customer's order will never exceed it.
