Visit Admin > Sales/Promos > Promotions

Go to the Actions tab, top right of the screen and then click on the Add Promotion link from the dropdown.

From here, there are a number of different Promo Code options available that can be configured. The most common Promo Code we see in use, is a simple discount, either percentage or fixed, for example 10% off your first order that can be sent out to a customer normally on a registration email or advertised on the site itself.
Additional options are listed below and of course a duration can be set tp determine how long the promotion is going to be running for.

Code – here you can input the promotion code that the customer can use during checkout process in order to obtain the discount.

One Time Use Per Customer – if the box is checked, then the promotion code can only be used once by a customer.

One Time Use Only – if the box is checked, then the promotion code will only work one time.

Discount – the discount field allows for either percentage off or fixed dollar amount off the price. (Maximum is 100% for percentage) 

Minimum Order – input a dollar amount here. This will be the minimum order threshold for your promotion to be applicable.  (Example: $100 – The promo code will be applicable if you spend $100 or more.  Or, you can leave the field blank, or enter $0, if you would like no minimum order amount).S

Start / End Date –   select a starting and an ending date for the promotion from the dropdown menus, or click the calendar icon to the right to easily select the times and dates.  Note: A start/end date must be selected for promo code to be applicable. 

HTML Code – enter custom html code here

Discount Type – here you can select by to apply the discount by Order, Shipping or Product. 

Discount Types offer you the ability to control what elements of the order the Promo Code is eligible for. Similar to the above, we most commonly see Promotion Type: Order being used, here the discount is applied to the Net Total of the Order. However it is important to note that Promo Codes can be configured to work only for Shipping discounts or even as far as only applying to certain Products.
