Once you have a promo code, you typically need to book online to get the deal. This is where we can help! You can use the CheckMyBus search engine to find bus routes for the day you’d like to travel. Then, you can filter your results by the bus company you have the promo code for. Then, when you click “view deal,” you’ll be redirected to the company’s webpage to make the booking on their site. While making the booking, you’ll typically find a field for promo codes which you can enter to apply the discount.
