I love a good detergent deal. Shaw's has Arm and Hammer laundry detergent on sale this week for buy one get one free. There is a shaws printable coupon HERE for 1.00 off 2, which you can stack with a manufacture coupon HERE. So buy 2, use 1 shaws coupon and 2 manufature coupons. Get one for FREE and 3.00 off the other one!!!
