A car parking group with sites in Leeds and Manchester is offering drivers the opportunity to pay with conkers.
Yes, you read that right. If you find yourself short of change – but inexplicably well stocked in Horse Chestnut seeds – you can use them to pay for your space, with each conker worth 20p.
Customers can hand over a total of 50 in any one go, buying themselves £10 worth of parking.
Staff at the car parks claim that they've brought in the scheme to help the environment and evoke childhood memories.
Sites taking part include the Merrion Centre and Clarence Dock car parks in Leeds city centre. Drivers in Manchester can use conkers in the Tariff Street car park, with 15 buying an hour's parking.
The company stated that each collected conker would be used to sponsor a UK forest in a bid to offset rising levels of vehicle CO2 emissions.
Ben Ziff, MD of Town Centre Car Parks, told the Daily Mail: "Car emissions are on the rise throughout the country.
"We thought it would be a fun idea to raise awareness and give a little bit back.
"We all have fond memories of looking for conkers so this seemed like a great idea for our customers. We are looking forward to seeing how many people bring us."
