Get ready to score enough laundry detergent to do 640 loads of laundry (or mix and match with other items.) Right now Amazon has a promotion to save $15 when you buy $50 of select household essentials. I went through all the items and my favorite deal (by far) is on Arm & Hammer Laundry Detergent. Right now the Arm & Hammer Liquid Laundry Detergent 224 oz 128 load bottles are on sale for $11.39 when you subscribe (reg. $19.99) and included in this promotion. You can pick up five and pay just $8.39 per bottle (less than $0.07/load) after sale, subscription discount and instant savings. You may also opt to just buy a couple and mix and match with other items in the promotion.
