Airmiles - Shop the Block - November 19 - December 28, 2020
There is not much about the offers available but you can check out which partners are participating at https://shoptheblock.ca/
Shop 3 of the offers for 300 bonus miles; 5 for 800 bonus miles; or 7+ for 1200 bonus miles between November 19 - December 28.
I was sent the BMO Mastercard offer to opt in early. It is Get 100 bonus miles when you spend $350 or Get 250 bonus miles when you spend $700 miles at participating partners.
I've got some planned purchases for Staples and Children's Place that I'm holding off on until I see what these offers are.
