Anyone want an Oxford tube ticket to London and back?

Hi! I accidentally bought an Oxford tube ticket (ticket covers a bus ride to London and then back to Oxford) and was wondering if anyone would be willing to buy it off of me? It expires Nov 6, 2026.

I paid £22.50, but would be happy to sell it at a discount! £20 was what I was thinking but this is negotiable.

Paypal would be ideal! Pls lmk if you're interested :)
