Every 4th Monday, Costco marks down a ton of product! These sales are not advertised, and they are different at every single location. They won’t last long either -just until they sell out. It can really vary, from household goods, to clothing, shoes etc. Good idea to mark it down on your calendar and head down early to score the deals! Here are some examples from the Regent location in Winnipeg – let me know what you find at your local store!
