Found 3rd Jan 2014
If like me you get fed up with paying for Air at petrol stations and having to find the change, Morrisons are offering a free voucher code with all petrol purchases over £15. This is an ongoing deal but you have to ask for the voucher at the tills. Found at Great Harwood filling station but they said it is a national deal. Not a major saving but paying for air should be free especially with the rising cost of fuel.
