This was their announcement last Thursday (24th April):-
... First Aberdeen, today launched a new voucher initiative designed to raise money for a good cause and encourage more people to use the bus.
20,000 households across the city will receive a leaflet this week from First Aberdeen which contains a free £1 travel voucher that can be used on any First Aberdeen bus service.
First has promised that for every voucher redeemed, it will donate £1 to Macmillan Cancer Support. This will help Macmillan continue to provide practical, emotional, financial and medical support to around 7,000 people living with a cancer diagnosis in the city, so that no-one has to face cancer alone.
In 2013 the company will be investing in a number of brand new buses.
