I found Ensure Active Nutrition Shake four-packs on clearance at Walgreens! They were $9.99 originally but are now on clearance for $4.99. Plus, there are some high-value coupons to use on top of this great clearance price. Use a $3.00/2 Walgreens coupon from page 18 of the Nutritional Drinks and Shakes Book. In my store, this book was with the health drinks and shakes. Also use two $3.00/1 newspaper coupons, bringing each four-pack down to just $0.49! Remember, clearance prices and inventory may vary by store.
