A car boot sale will fundraise for the life-saving Herts Air Ambulance.
All admission fees from the Northchurch sale this Sunday will go to the good cause.
Organiser Charles Elliot said: “We are hoping to do a charity car boot sale once a month depending how we get on with this one.”
The sale, off Hamberlins Lane, runs from 9.30am for sellers and 10am for buyers.
Admission costs £8 for cars and £12 for vans and shoppers will be asked for a 30p donation.
