Shop end-of-season deals
A common practice of retailers, Costco included, is to sell large season items at really good prices. For example, now that summer is over, you can find patio furniture, pool toys and other summer closeouts that stores need to get rid of to make room for fall merchandise.
Camping gear is another type of merchandise that is marked down but can still be used this time of the year. Don’t hesitate to stock up for future nature outings!
