10% off all the car parks at
www.parkandgo.co.uk - the voucher code PRV1. HAve used Luxury Meet and Greet service few times, very well!
Park and Go Mabchester (in Carrington) - well, sometimes half the price of others, and secure enough, but transfer...extra hour will be not too much to add, though for those on a tight budget like me worth considering, especially for longer parking (2 weeks and more).
