I had to cancel a bus ride with FLIXBUS (https://www.flixbus.com/ bus in) and got a $79 voucher refund. Unfortunately, I do not plan to travel soon and would like to resell it for $50 for anyone who has plans to take a bus soon. The voucher is valid for 1 year and can reduce your ticket price by $79. The voucher balance can be split into multiple tickets till it's exhausted. FLIXBUS is 100% electric and pretty comfortable for longer rides. Thanks!
