Hi,

In the settings of the coupon, you have one called "quota" and another called "quota per user".
If you set a number in the quota setting, the coupon will be usable for that number of times regardless of who uses it on your website.
If you set a number in the quota per user setting, the coupon will be usable for that number of times per user.

Works Perfect! Many Thanks!
