I did get the most recent Aeroplan booklet, which among othre offers, had a standard offer for Avis with 2 coupon numbers, which must be available to all Aeroplan members :

1000 Miles with rental - coupon MCAA014

1500 Miles with rental & Where 2 GPS system - coupon MCAA015

There is no limit to how many times you can use these, no other restrictions, other than dates they are valid (Sept 15 - Nov 15). Midsize Group and higher must be booked.

Avis will be getting all my rentals in Sept/Oct/Nov as a result, even though they did not include me in their targetted promo

Hopefully many other FT'ers can use these to crank up some pre Xmas AP points
