Just tested the code for a one way rental on Avis.ca from my location in downtown YYZ to the airport and the regular rate on a one day rental was $55.00 plus tax ($76.65 total) for a sub compact. Using the code it came out to $27.99 plus tax ($46.13) for the same car. Savings of $30 sounds like a good deal to me as the surcharge of almost $13.00 CAD doesnt seem to be going anywhere anytime soon so use the code and keep some money in your pocket!!
