Costco's current hero offer is the Labor Day Sale delivering $60 off when you spend $200, making it ideal for anyone stocking up on bulk items during the promotional period. The site also hosts a range of tiered deals that reward larger baskets and category specific purchases, so your best saving depends on what you're buying and how much you're spending.
Smaller shop under $100: If you're grabbing a few essentials, the Labor Day Sale offering $25 off at $100 spend is your best bet among the general promotions. Alternatively, if you're shopping for apparel specifically, buying 5 to 9 items gets you $20 off, which may edge out the Labor Day threshold depending on your basket mix.
Shopping between $100 and $200: The Labor Day Sale's $25 off at $100 applies here, but you're approaching the higher tier. If you can reach $200, hold off—you'll qualify for $60 off instead, which is substantially more generous. If you're buying multiple big ticket items rather than reaching a spend threshold, the bundle deals might work better: $100 off when you buy 2 items, $200 off when you buy 3, or $300 off when you buy 4.
Spending $200 or more on general shopping: The Labor Day Sale's $60 off kicks in and is your headline offer. However, if you're targeting specific categories, check whether a category deal beats this. For appliance purchases over $1499, the Spend and Save promotions are stronger: you'll get $200 off at $1499, scaling up to $300 off at $1999 and $500 off at $2499 or more. Furniture shoppers can benefit from up to 25% off, and outdoor toys go up to 30% off. If you're buying a Sealy Posturepedic Plus Prosser Hills mattress, look for $130 to $200 off that specific model.
Bulk apparel purchases: The apparel deals offer $20 off for 5 to 9 items and $50 off for 10 or more, which may outperform the general Labor Day thresholds if clothing dominates your basket.
Only one offer applies at checkout, so compare what's available for your specific items and basket size, then claim whichever produces the larger saving.
