Begin by following the steps in Basic Promotion Setup.
If you selected the "$ off order" option for Promotion Type, then under Rules you will enter a dollar amount. This amount will subtract once from the final order total.
Unlike a percentage off order, this will apply to both ticket price and service fees.
iTickets always collects the regular service fees on these orders. Therefore, we do not recommend that you offer this type of discount for an amount greater than your lowest available ticket price.
If there is no max lifetime discount, leave that field blank. Once finished, click Add.
Note: Please test the promotion using the customer order form, and try all possible scenarios. Make sure that you proceed at least to Payment, to confirm that the discount is working as expected.
