Sears has Ultra Wash detergent on sale 1/2 price
The sale goes through Saturday (tomorrow), July 23.
I got an ad in the mail yesterday, which says this sale is available at my local Sears appliance store. I don't know if the same sale is available at Sears mall stores or online.
The box pictured is the orange Stain Fighter box, 120 washes, but the ad sounded like it includes all formulas.
