Knowing that you get the same coupon result either way, can help with the troubleshooting.
I removed the the regulations, entered the coupon code, clicked APPLY and no coupon confirmation message either, so I'm guessing T&C box has no effect on this. I do need to have the regulations set to true though. I'll keep on working on the suggestions and see what I get.
