Tourists come from far and wide to the coast to take in a breath of fresh seaside air.
However, one person has come up with a bizarre way to cut out the travelling for these people, while still letting them fulfil their wish for a coastal whiff.
For just £10 - plus postage - you could buy a jar of seaside air, fresh from Caister beach.
An advertisement on auction website eBay is flogging fresh air, sealed in a jar from the beach.
The advert says: “Hand collected early morning when the air is fresh.
“People come from all over the world to breathe this air, being fresh, invigorating and fortifying to the whole body.
“Walkers enjoy this, now you can too.”
The seller claims to ship world wide, and that it comes carefully sealed in a jar - though buyers will also have to pay a £4.80 packaging fee.
