Staff at Sainsbury's in Haywards Heath are holding a family fun weekend in aid of Kent, Surrey & Sussex Air Ambulance this Saturday and Sunday (December 8th-9th)
A lollipop lucky dip, gingerbread house auction and Name the Bear competition will be among the attractions at the Bannister Way store which has chosen the life-saving helicopter as its Charity of the Year.
There will also be a raffle and tombola with prizes including Sainsbury's gift vouchers and a model Air Ambulance helicopter.
Haywards Heath Town Mayor, Cllr John Sabin, will be the special guest at 1pm on Saturday and there will be a visit from Air Ambulance mascot Dr Dudley.
Kent, Surrey & Sussex Air Ambulance needs £5million a year to keep both helicopters flying and relies almost entirely on public donations.
The pilots, doctors and critical care paramedics have attended more than 1,000 call-outs so far this year.
Air Ambulance Head of Corporate Relations Cheryl Johnson said: "We are delighted that Haywards Heath Sainsbury's is supporting us and it is fantastic to have them on board.
"Their support will help us raise not only much-needed funds but also valuable awareness about our life-saving service among customers and the local community."
