Costco's November coupon book runs Oct 19 – Nov 15

The November Member-Only Savings book covers Oct 19–Nov 15 — warehouse savings that apply automatically for members, no coupon clipping needed.

Costco's November Member-Only Savings book is set for October 19 through November 15, 2026, according to ad-tracking coverage: GottaDEAL posted the November ad listing on October 11, and HotCouponWorld lists the same 'Costco Ad 10/19/26 – 11/15/26' alongside the current book that runs through October 18 — so the new book starts the morning after the current one ends, with no gap week.

Early previews of the November book's contents are surfacing: one preview lists a LG top-load washer and rear-control dryer set $500–$1,000 off, Citracal Calcium Citrate + D3 $4 off, Downy Unstopables $4 off, and One a Day 50+ multivitamins $4 off, alongside an 83-inch LG OLED TV priced at $3,299.99 in the ad.

The standard coupon-book mechanics apply: savings come off automatically at checkout for members both in-warehouse and online, with no physical coupons to clip and no flyer to present. Shoppers generally get better prices in-store than online, so warehouse visits are usually the move for the big-ticket items.

Costco's November book is separate from its Black Friday waves — deal trackers expect the first wave of Black Friday deals to start leaking in late October, so this book is the warm-up, not the main holiday event.
