Marvel fans are trying to cash in on the hype surrounding Avengers: Endgame by reselling prime tickets at exorbitant prices that would make even Tony Stark do a double take.

The highly anticipated film, which caps off more than a decade of filmmaking for the movie studio, is set to hit theaters later this month and is expected to rake in $200 million to $250 million in its opening weekend, Variety reports. And thats a relatively conservative estimate, as Deadline projects the superhero film could debut closer to the $300-million mark and become the highest-grossing domestic opening of all time.

When pre-sale tickets for the film were released this week, multiple theater chains like AMC and Alamo Drafthouse revealed demand had crashed their websites.

Fandango later reported that Avengers: Endgame scored the best first-day U.S. sales record for the online ticket retailer, unseating Star Wars: The Force Awakens in a mere six hours.

Naturally, seats on opening night are hard to come by, so fans have started to resell movie tickets for thousands of dollars.

Two tickets were purchased earlier this week for $15,000 on eBay for a dine-in theater experience to catch the film in New Jersey.
