Costco Markdown Monday Calendar 2026

Every 4th Monday Costco marks down items first thing in the morning. They will not be highlighted or show a discount, but you'll know that they are marked down because they end in .97.

This is my 9th yearly calendar for markdown Mondays, and have been shopping it for a while before that. So it's definitely not a new thing.

Some of the best deals I've ever found have been on those days.

It's at all the stores across Canada, and it's in every area of the store too.

I post up all the deals I find at my local store on those Mondays, but make sure to check your stores too as it's different at every location. You cannot price match these to another location, and once they're gone they're gone.
