For discounts you want to carefully control, you can create a single-use promotional code. This will allow the code to be used only once, rendering it invalid after it’s been used.
- On the main calendar window click Manage Schedule.
- At the bottom of the screen click the Promotions button to bring up the Promotions window.
- Select the promotion you wish to add a code for and click the Edit button. This will bring up the Edit Promotion window.
- Select the Codes tab.
- Click the Limit each code to a single use checkbox. This will limit any codes entered to being used only once.
- Click OK to finish.
