A couple of days ago, I was doing a small transaction at Walgreens and I received a Catalina coupon for 5,000 extra Balance Rewards Points on a $15.00 purchase! The Catalina coupon is valid for three days after you receive it, and it varies by person.

I earned the extra 5,000 Balance Rewards Points when I bought Almay, aspirin, Bic pens, Wet n Wild and Herbal Essences, and my shopping trip was a moneymaker. Check it out:
See the moneymaker Almay deal here.

Total before manufacturer coupons: $17.99
Total paid out of pocket: $5.99
Total after all rewards and rebates: $0.99
Received: 5,000 Balance Rewards Points ($5.00) with the Points Booster Catalina coupon for spending $15.00 before manufacturer coupons (received in a previous transaction)
TOTAL COST: $4.01 Moneymaker for all 10 items worth $20.98!
