Coupon configuration: "Individual use only"

When configuring a new coupon, there is a tick pox for "Individual use only" in Optional Fields. I can't find any explanation of this in the current documentation at https://awodev.com/documentation/awocoupon-pro/coupons.

Please explain what this option does and how it would be used.

Thanks,

Allen

Only really applicable if you have multiple coupons enabled.  If checked, then every other coupon in the cart will be removed (including automatic discounts) and apply just that one coupon.
