Very cool.
Here's the link: https://airmilesmegamiles.ca/en/

If you shop at 5 sponsors, you get 1250 Air Miles ($125 value).
New option this time:
If you shop at only 3 sponsors, you get 650 Air Miles ($65 value).
I find that getting the 4th and 5th merchants are the hardest, so that's a nice fallback.

Here are the merchants I’ll attempt for the cards I manage. (These are based on Manitoba options; your options may differ.)

REWARDING YOUR OPINIONS • Need to join the survey program, and maybe do one survey.
BMO AIR MILES MASTERCARD • I still have this card from my last churn. Need to make any 20 transactions, of any amount. If I’m in a pinch, it’ll be 20 purchases for in-app local street parking at 5 cents each. Must “opt in” on the website.
HUDSON BAY: Register to auto-convert Hudson's Bay Rewards points to Miles (also +10 Air Miles)... I don't shop at The Bay, so, sure, why not?
SHELL • Buy 25 L gas.

SAFEWAY PHARMACY • Buy $10+ of pharmacy items.
SAFEWAY: $60 spend (also 5x Air Miles)
SOBEY’S: $60 spend (also 5x Air Miles)
STAPLES: $75 spend (also 10x Air Miles)
HUDSON BAY / HOME OUTFITTERS: $50 spend (also +25 Air Miles)
REXALL: $40 spend (also +40 Air Miles)
