This week Andersons has Arm & Hammer Laundry Detergent on Sale for $2.99. This is for the 50 oz size. Several varieties to choose from. The regular price is $3.50 each.
The deal gets even better when you combine it with the coupon below to save $2 off your purchase of 2. The cost prior to coupons is $5.98 plus tax, after it is just $3.98 plus tax. This makes each one $1.99 plus tax. There is a limit of 2.
In the ad they are also offering 20% off one item. I tried this with this deal before one cashier said yes the other said no. Up to you if you want to try this or not!
