My parents put up thousands upon thousands of AMs a year because of my dad's meds combined with Safeway bonuses (although who knows how long that will last with other provinces eliminating points at pharmacies). They got their onyx card and my mom was pretty chuffed about it, but I looked at the benefit sheet and I'd say it's about as useful as Aeroplan dBlack.
Discounts on a couple flights you'll never use, discounts on selected toasters, invitations to events you'll never attend. Wow.
