The P&G Rebate (August–September)
Separate from the coupon book: buying $100+ of qualifying P&G products (Tide, Bounty, Charmin, Cascade, Dawn, Oral-B, Gillette, Crest) earns a Costco Shop Card. This stacks with the coupon book discount if both run simultaneously — which they do each August–September.
Data covers March 2023 – May 2026. Coupon books run ~every 4 weeks (12 per year, 26–28 days each). US warehouse books only; warehouse-only items and regional variations exist. Retail prices change independently of discount structures.
