As advertised in this week’s Walgreens ad, Windex spray cleaners are on sale for $3.00. Buy two and receive 1,000 Balance Rewards Points, worth about $1.00 when later redeemed. Plus, I’m happy to report that a purchase of two Windex sprays is generating both a $1.50 Register Reward and a $1.50 Catalina! Both of these rewards are unadvertised from two different Catalina offers. A Catalina and a Register Reward are basically the same thing; they are both coupons that print at checkout and can be redeemed on a future shopping trip on almost anything in the store.
