A familiar friend is set to return to the streets of Sydney later this week with Triple M relaunching the Triple M Rocks bumper sticker. The stickers will be available from McDonalds outlets from Friday the 16th of May and Triple M are giving listeners the chance to share in $40,000 cash prizes. To win your share - up to $10 000 - just listen to the station for the Triple M strip-song! Terms and conditions here.
