Amazingly enough, this Air Miles offer seems pretty good.
And even if you won't admit that you still have an Air Miles card, you know you know someone who does.

During May 2017, use the special coupons and shop at 5 different Air Miles Partners to get an additional 1,250 Air Miles bonus miles. The offers vary by province. The offers I'll probably use are:
Staples, $45 spend
Rexall, $25 spend
RONA, $60 spend
Shell, 25L purchase
Texture magazine app: Free 1-month subscription... maybe buy a second month at $10/$15.

Even if you use Air Miles for Cash Miles , I calculate that value to be $131.
You also get the bonus miles for each particular offer, too.
