Double Discounts

How can I prevent someone from hand jamming 2 discounts into one order?

Any way to program an coupon to be nulled when another discount is detected?

For instance, newsletter discount and a holiday sale discount should not even make it to checkout.

Re: Double Discounts

Zen Cart only allows one coupon to be redeemed against the current order. If you try to redeem another coupon, it replaces the previous one entered.

If you have added custom order-total modules to do additional discounting, you'll need to write custom code to check whether the other modules are in use with the current order.
