one coupon per customer

I got a problem,

i have customers using 3 coupons at a time and the order comes out to just about free for them.

how i can make it so they can only use one coupon ?

You don’t say which version you are using, but 1.3.5 sp3 has this option.

Settings>general>discount>Allow customers to use single discount coupon only

Also, you can select in the discount coupon itself the customer can only use that coupon once if required.


sorry yes it is 1.35 and that was what i was looking for.
