It's not a great program, but it's still worth it to be a member. Sometimes Safeway has some good deals where the air miles they hand out are worth more then the product costs. Prescriptions are another thing, but since I don't have many prescriptions, and I have to pay 20%, it's cheaper for me to go to Walmart.

Generally speaking, you're better off with other programs. Buying gas from PetroCan and using your Sears Card will give you Petropoints and Sears points. If you spend $4000/year ($333/month) on gas, then you can get the $360 Sears card every 2 years. That's a return of 4.5%, and it beats any other Credit Card + Gas loyalty program.

There are a few more bright spots, other then the prescriptions. The first is car accidents. If you live in BC or Calgary, Craftsman Collision gives Airmiles. So your insurance company pays for the damage, and you get the Airmiles. Another one is Iris optical. It's more expensive then other eye centres, but if your extended medical pays 100%, then you might as well get the Airmiles.

The best thing to do with Airmiles is to transfer them into Priority Club points and use the points for Points Break stays. That way it only costs you 300 Airmiles to stay in a hotel. Otherwise, you'd only get about $40 in gas or grocery cards.

It's worth it to collect Airmiles on things you buy anyway.

BMO Airmiles Mastercards are generally a waste of time.
