Your best friend decided to splurge $500 for a front-row seat ticket to their favorite band playing in town in a few days. Something urgent came up and they are now unable to go. Due to other concerts and events happening the same day, ticket prices have dropped significantly and your friend's ticket can only be sold for $300. Your friend has tried selling them to other friends/family to no avail. Your friend comes to you for advice - they don't want to lose money but they can't go to the concert. Give your advice.
