The short answer
Type it in the Discount code box at checkout. A message tells you if it worked or why not: not valid, expired, not active yet or fully used.
Where to type a code
Checkout
- Click Discount code
- Click Check the message
Discount shown above the total
At checkout, type the code in the Discount code box. The message under the box says what happened.
- Codes reduce certificate fees. Courses are already free.
- A code works only on the site it was made for. A code from another EDWartens site is not valid here.
- If a code is not accepted, the message says why: not valid, expired, not active yet, or fully used.
- A percentage code works in every currency.
- A code that takes off a fixed amount, or sets a fixed price for the whole cart, cannot be used on a cart charged in pounds, euros or another local currency. You will see "That code cannot be used on this order."
- A discount code cannot be combined with the multiple-certificate discount on the same certificate. One saving applies at a time.
