Elon Musk’s ‘zombie-killing’ flamethrowers are already available to buy on eBay – less than 48 hours after the first batch was picked up by customers.
The Boring Company-branded flamethrowers are listed on the auction site with prices ranging from $3,000 (£2,200) to $20,000 (£14,900).
That’s around 40 times the original $500 (£374) price tag.
An instruction manual for the gun is also available on eBay for $250 (£187).
Elon Musk sold a limited run of 20,000 flamethrowers back in February to raise $10 million (£7.02 million) for his high-speed tunnel venture, the Boring Company.
The firm plans to build a network of tunnels where vehicles are transported on electric skates to their destination, reducing traffic on the surface.
Musk had earlier sold 50,000 hats to help raise money for the project.

Musk tweeted photographs of excited fans shooting flames from their new toy.
It’s unclear when the next batch of flamethrowers will ship to customers.
As the promotional device started to land with customers, Musk posted a safety warning to customers on Twitter, stating: ‘Please use as directed to avoid unintentionally burning things down.
‘For simple & concise instructions, we drew upon wisdom in great Dr Seuss book “Green Eggs and Ham”.’
It continued: ‘I will not use this in a house, I will not point this at my spouse, I will not use this in an unsafe way, The best use is créme brulee.’
Earlier this year, Musk revealed he had hastily re-branded the guns to ‘Not A Flamethrower’ after a number of customs agencies stated they would not ship any packages labelled as ‘Boring Company Flamethrower’ to customers in the mail.
Each of the 20,000 Boring Company flamethrowers has a unique serial number. Elon Musk has previously teased plans to follow-up the promotional stunt with a ‘freezegun’

Elon Musk’s flamethrowers do not use a mixture of flammable liquids to launch flames great distances, like its military counterparts.
Instead, the Boring Company torch guns function like large propane blowtorches.
Musk has previously joked that the flamethrowers will be ideal for an impeding zombie apocalypse.
Ahead of the original launch of the gun, he said: ‘When the zombie apocalypse happens, you’ll be glad you bought a flamethrower.
‘Works against hordes of the undead or your money back!’
Following the success of the flamethrower, Musk has started to tease the next Boring Company promotional product.

Elon Musk hinted at the Boring Company’s plans to launch a ‘freezegun’ in a tweet back in January.
The Boring Company has proposed to build a tunnel through West Los Angeles, passing underneath Sepulveda Boulevard through Culver City.
According to the company, the privately-funded tunnel would be able to transport cars at 150 miles per hour (240 kph) to help with LA’s ‘soul-destroying’ congestion.
It’s unclear how much a round-trip would cost, but the Boring Company said it will be ‘comparable to or lower than current public transportation fares’.
