Fans of Tottenham's Europa League opponents have been trading buckets of fish and reindeer meat for a ticket at Thursday's game.
Around 50,000 wannabe Bodo/Glimt supporters have been competing for 480 general sale tickets available at the club's 8,270-capacity ground.
The Norwegian champions are looking to overturn a 3-1 deficit from the first leg and reach their first European final.
Torbjorn Eide, a production boss at a fish farm in Torsken, told Norway's state broadcaster NRK that he offered five kilograms of semi-fried boknafisk for a ticket.
The haul of fish, worth around £181, managed to tempt a fellow fan into giving up their seat.
