Costco September 2026 grocery finds: What are the best deals and discounts you can get now?
New bakery items, pantry staples and member savings are filling Costco warehouses this month.
Costco's September 2026 lineup includes a mix of new grocery finds, returning favorites, and limited-time discounts, giving members plenty of reasons to make another warehouse run.
Some of the most notable new arrivals are in the bakery and pantry aisles, while Costco's current member savings also include discounts on snacks, breakfast products, and ready-to-cook foods.
One of the biggest bakery talking points is the Costco Buttermilk Biscuits, which are sold in packs of 10 for $6.99 at select warehouses.
The new Twice Baked Cinnamon Filled Croissants are another standout at $11.34, with one shopper describing them as "the most superior thing the Costco bakery has made, 12/10."

Kirkland Signature Semi Sweet Chocolate Chips have also returned after being discontinued in 2024.
A 4.5-pound bag is currently priced at $13.61, making them a particularly useful option ahead of the fall baking season.

What are the best Costco discounts this month?
Costco is also running member-only discounts through September 20.
Amylu Paleo Andouille Chicken Sausages are $4 off, while Kodiak Cakes Power Cakes Flapjack and Waffle Mix is also discounted by $4.
Goldfish Baked Snack Crackers are $3.15 off for a 66-ounce box, making the bulk pack one of the stronger snack deals currently available.
Southern Living also highlights a $2.40 discount on Dawn Platinum Advanced Power Dishwashing Liquid, although that falls outside the grocery aisle.
That means September's strongest food value isn't limited to one category.
Members can choose between new seasonal bakery products, bulk pantry staples and temporary discounts on everyday foods.
As always with Costco, availability and pricing can vary by warehouse, and several of the September finds are only available at select locations.
