Costco is the nation’s largest warehouse superstore and accepts neither newspaper nor Internet printable manufacturer coupons. Instead, Costco offers a warehouse offer booklet for discounts on specific items throughout the store, only valid on specifically listed dates.

Watch for warehouse offers throughout the store on items like meat, produce, dairy and baby gear for maximum savings. Warehouse offers tend to rotate monthly and expire mid-month.

Be sure to steer clear of health and beauty, dry goods and cleaning supplies, as these are generally priced lower at supermarkets and drug stores.
