Avis charges different rates to different types of renters. They make no secret that weekday rates are generally higher and weekend rates are generally lower, commensurate with demand.
AFAIK, the Weekender Club is aimed at people who don't own cars and is meant to stimulate business from leisure renters who would like a car on weekends only in their home city. These renters get 4 rentals for the price of 3 and reliable transportation on weekends, Avis generates revenue from assets that would otherwise be sitting in a lot depreciating. I think it's a brilliant scheme as I fell into their target market when I was living in YYZ and liked the ability to pick up a like-new car for the weekend, get away from the city and not have to worry about parking from Monday to Friday.
If your rental encompasses both the slow weekend periods and the more lucrative work-week periods when Avis can normally charge a higher daily rate, then you really aren't generating that high marginal revenue that Avis is targeting with the Weekender Club. Avis charges special weekly and monthly rates to people in your situation that strike a balance between offering you an attractive cost per day, while charging enough to make it worthwhile to forgo the potentially higher short-term rates they could hypothetically charge from business renters.
Of course, that's just my opinion.
