Entering a voucher code to obtain discount

[cja]

Before I decide to purchase the full version of Actinic I would like to know whether it is possible for a customer to enter a voucher code (which they may have obtained from eg. an advertising leaflet) at checkout which then automatically gives them a discount on their purchase.

Any advice would be much appreciated!
