FREE parking for 30 minutes and a £1 charge for the evening in Penzance are just a couple of the changes being trialled in Cornwall's car parks.
A number of changes in council-owned car parks are being made as part of a series of parking offers.
The offers, which begin on Saturday and run until April 20, have been developed in response to calls from local businesses.
In order to take advantage of the free 30 minutes' parking offer, which will be available in every Cornwall Council-run car park, motorists will need to use the RingGo mobile phone payment service.
A spokesman for Cornwall Council said: "Although this system is very easy to use, first-time users will be required to provide some initial information and so they may find it easier to register online at www.ringgo.co.uk"
Other offers being made by the council during the trial period include reduced season ticket charges in council-run car parks in 45 towns and villages, changes to the winter parking charges in St Ives, a reduction in day charges in less heavily used car parks, a £1 evening charge after 6pm in Penzance and changes to the tariff structure in force in car parks in Hayle.
Bert Biscoe, the council's Cabinet member for transport, said: "These trials are an effort to understand what measures, when and in which places, we can use in future to enhance trading, improve accessibility for people needing to come into town centres for services, and to sustain car parks income to contribute to the maintenance of the road network."
