I am trying to use the Avis Australia coupons from here: http://www.avisholidaypass.com.au/vo...85200&ID=25439. However, when I enter the AWD and coupon, I get this message:

"YOUR COUPON MUST BE REDEEMED AT THE COUNTER

This coupon will not be reflected online. To redeem your reward, please present your paper coupon at the rental counter.

Some advance reservations are required. If this is noted in the terms and your coupon is associated to an AWD, please enter this AWD with this reservation to ensure you receive proper adjustments at time of pick-up.

Check coupon for full Terms and Conditions."

Anybody have experience with this? How do I know the final cost this way?
