GeoZone for Coupon?

Hi, is there an extension that gives a Geo Zone for a coupon? I need to create a coupon but it is only valid for one geo zone.

You could use Ultimate Restrictions for this. You could limit the "Coupon" Order Total to be disabled when a particular coupon was used outside of a specific geo zone. They wouldn't get an error message (because it removes the line item itself, not modifies how the Coupon system works) but they wouldn't be able to use the coupon.

Feel free to take a look at the screenshots and demo site, and if you're interested let me know at www.getclearthinking.com/contact if you have any further questions.
