Costco Canada Markdown Monday Calendar 2027

Every fourth Monday, Costco does markdowns at stores across Canada. These are not advertised, and you have to look for items ending in .​97.

They have been doing this for a long time, I've been posting them for many many years, and I think this is my 10th year of the calendar for it. So it's definitely not something new.

But they are changing things around, there's markdowns on random days too. So always keep an eye out when you're there.

I always post those up on Facebook and here. So make sure to follow And also you can check out the calendar for 2026.
