They automatically included an extremely overpriced insurance policy with your ticket and make it easy to miss during your purchase. It added 15% to the price of the ticket. They won't refund the insurance policy voucher even if it is long before your trip. It is a dishonest and unethical business practice purposefully designed to rip you off.
If you look at the fineprint other insurance policies you might hold take precedence. I purchased the ticket with a Visa card that includes $500,000 of insurance automatically versus the paltry $12,000 from the included policy. If you have any type of travel health insurance you also don't have a need for their overpriced policy.
There are other better companies to book a bus ticket with.
