I was able to get Wisk 3X concentrated laundry detergent 32 load, 32 oz. bottle for $3.49. After the $3 Red Plum coupon from Aug 29, it cost me just 49 cents per bottle.

I was shopping at the Tops in North Tonawanda (Western New York), I bought the last 3 bottles at that location.

I found it on the top shelf just above the newer design bottles of Wisk in the detergent aisle. Hope you can find some, too!
