If you take just one lap around the Costco discount section, you will find 507 items on sale, with prices dropping by as much as 621 TP3T for some. However, it would be a mistake to assume that all stores and all items have become that cheap just by looking at these numbers. Discount end dates vary by item, and since the fourth week of October coincides with store closures, you might end up making a wasted trip if you time your visit incorrectly.
In this post, we will organize the confirmed discounted items at Costco from October 19 to 25, 2026, by price range, and also look at which products you should buy first and when the store is closed.
Until when does the Costco fourth week of October discount period end?
The discount verification period is from Monday, October 19, 2026, to Sunday, October 25. During this period, approximately 507 items are included in the discount, with discount rates of up to 621 TP3T applied depending on the item.
However, this figure of 62% is not applied universally to all items, but is based on the item with the highest discount rate among the discounted products. In reality, since discount rates vary significantly by item, if you are targeting a specific product, it is more accurate to check the price and discount end date of that item separately.
What are the discounted food and snack items and their prices?
In the snack category, Campfire Marshmallows 1kg is being sold for 4,990 won, and the discount on this product ends on October 25. Be Kind Dark Chocolate Nut Bar 480g is 12,990 won, and the discount ends on October 31, giving you more time than for the marshmallows.
General Mills Fruit Guscious Jelly 1kg is currently on sale for 14,790 won, and the discount also ends on October 25th. As such, end dates are mixed even within the same snack category, so if you plan to buy multiple items at once, it is efficient to check the products with the earliest end dates first.
How can I compare the price ranges of rice and household goods?
In the food ingredients section, Daegu Nongsan rice flour 2.5kg is being sold for 5,990 won, and the discount ends on November 8. A pack of three 400g Bonduel peas is priced at 6,990 won, and the discount on this also continues until November 8.
The Chungjungone Hongcho Lemon & Lime 900ml x 3 pack is priced at 11,470 won, and the discount ends on November 1st. Since the discount period for all three of these items remains until November, you can postpone your purchase a little compared to the products ending on October 25th.
How do I distinguish between the listed price and the discounted price on online malls?
On the official Costco online store, Bibigo King Dumplings 1.925kg x 2 packs are listed at 32,990 won, and CJ Round Hetban 210g x 36 packs at 42,990 won. Kirkland Ultra Laundry Detergent 5.73L is listed at 19,490 won, Maxim Mocha Gold Coffee Mix 210T x 2 packs at 61,900 won, and Momos Coffee House Blend 1kg at 33,990 won.
It is important to distinguish that these prices are the selling prices displayed on the online store, not values with separately verified discount status. Since this differs in nature from items like the marshmallows or jelly mentioned earlier that have specified discount end dates, it is necessary to double-check the actual discount indications at the store or online store to avoid mistaking household goods for discounted prices.
How are purchase priorities divided based on the end date?
Based on the discount end date, items are broadly divided into two groups. For the group of items like marshmallows and Guscious jellies, which end their discount on October 25, you must visit within this week to purchase them at the discounted price.
On the other hand, for groups like nut bars, peas, red vinegar, and rice flour, which are on sale until November, you can take your time visiting. If you organize your shopping list by separating these two groups, it becomes easier to distinguish between items you must buy this week and those you can purchase next week.
How can I check Costco's closing days and differences by store?
Some Costco stores are scheduled to be closed on Sunday, October 25. This closure does not apply to all stores, and closure status and operating hours may vary by store.
Additionally, discounts and stock availability may differ between online and offline stores. If you are planning a visit with a specific item in mind, it is safer to check the store's operating status and stock availability before you depart.
