This week at Walgreens, several different varieties of Elmer’s Glue are on sale for $0.99. The Elmer’s Purple School Glue is included in the sale. (It regularly sells for $3.99 at my store!) For the best deal, buy three three-ounce bottles and use a $0.55/3 Smart Source newspaper coupon. The final price will be $0.81 each.
