Costco is rolling out more hot September deals—here are 10 worth picking up before they disappear
- Replies 0
Here comes another round of savings at the warehouse giant for September. Shoppers can expect more of everything, from comfort foods and protein-packed snacks to cleaning staples and unique kitchen finds.
And the timing couldn’t be better, as colder weather is creeping in and households are stocking up for the busy months ahead.
On top of that, Costco is marking 30 years of its Kirkland Signature brand, giving members another reason to celebrate their fall shopping trips. That’s three decades of unbeatable value, quality, and those giant tubs of peanut butter we all secretly love.
So, grab your membership card, dust off your shopping list, and let’s dive into the best deals making waves this month.
Saffron is the world’s most expensive spice, but this month, you can snag a 14-gram jar of Full Thread Greek Saffron for $59.99 (regularly $79.99). If you love to cook, this is a rare chance to elevate your risottos, paellas, and even your morning tea. One customer raved about the aroma and quality—so why not treat yourself to a little culinary luxury?
The fan-favorite Nongshim Tonkotsu Ramen Bowls are on sale for $10.39 (down from $13.99). These bowls are perfect for a quick lunch or a late-night snack, and you can always jazz them up with leftover chicken or veggies. One shopper confessed to drinking the broth straight from the bowl—no judgment here!
FITCRUNCH Protein Bars are on sale for $17.29 (down from $22.99). With less sugar and a flavor that’s got shoppers hooked, these bars are perfect for tossing in your bag or keeping in the car for those on-the-go moments.
Treat yourself to a little Italian flair with San Pellegrino’s Melograno & Arancia (Pomegranate & Orange) sparkling drinks. A case is just $18.99 (down from $23.99). These are perfect for entertaining, or just sipping on the porch as you watch the sunset. One customer buys them by the case—need we say more?
A clean kitchen is a happy kitchen, and Costco’s got a deal on a one-gallon jug of Dawn Professional Dish Detergent for $15.79 (down from $18.99). It’s gentle on sensitive skin and tough on grease—plus, if it’s good enough for cleaning up after oil spills, it’ll handle your lasagna pan with ease.
