Only one discount at a time

[tough_chik]

I have a 20% discount code out and now I have a product discount code. Is there a way that I can limit the code so that the consumer can only use one of the discount codes and not both at the same time?

Thanks,

Shannon

If the 20% discount is a cart wide discount, then there is no way in our system to keep a buyer from entering in both discounts. However, if both discounts are product specific or cart wide then our cart will not allow both of them to be used.
