Template Tags: Discounts & Coupons/Vouchers

CartThrob can handle both discounts (which are automatically applied) and coupons/vouchers (customer uses a coupon code to register a discount).

Coupons can be added and removed from the cart. Discounts are processed automatically based on the cart contents or other factors and can't be removed, except by the discount itself being removed or disabled.

Coupons/vouchers information

One limitation of the current system is that there is no tag that will output information about any currently active applied discounts.
