restrict coupon codes for only one time use in magento 1.9.0

Question

For orders above 200, we are giving free shipping on our site.

We would also like to have a "Free Shipping " coupon code applicable to orders below 200

I gave Uses per Coupon : 1 , Uses per Customer : 1

(see attached image) but still for registered customers also, can use coupon codes many times and buy the product.

Where is the problem?

Answer 1

To apply that rules to guest user, you need to also select NOT LOGGED IN at Customer group multiple options.

Magento counts this as guest customer.

Uses per Coupon

The number of times the coupon code can be used.

Uses per Customer

Determines how many times the coupon code can be used by the same registered customer who belongs to any of the selected customer groups. The setting does not apply to guest shoppers who are members of the NOT LOGGED IN customer group, or to customers who shop without logging in to their accounts. If there is no limit, leave the field blank.
