Walgreens offers the Purex Ultra Natural Elements Liquid Laundry Detergent 50-oz. Bottle in Linen & Lilies for $1.99. Plus, Balance Rewards members can clip the $1 off coupon on the product page and add two bottles to cart (100 oz. total) for $2.98. (Not a member? It's free to join.) Choose in-store pickup to dodge the $5.99 shipping fee. That's $1.49 per bottle and a buck less than you'd pay for just 75 oz. of this detergent in other local stores. This hypoallergenic detergent is free of dyes and made from 95% naturally sourced ingredients. Deal ends April 22.
