Litres for Education is a program that is run nationally and is a fundraising program for charitities.
Certain petrol stations have signed on to support the initiative. Users then print a Litres for Education window sticker which they point out to petrol attendants at the designated petrol stations when they fill up. The station then donates 10c a litre to the user's chosen beneficiary.
SADD is a beneficiary of this initiative and you can support SADD simply by displaying the window sticker below on your car and buying petrol from a designated station.
