Now, I've never priced them in the grocery store but I imagine they are a bit high. But, not only did I get to do 2 loads of laundry for free but I just threw one of these sheets in the washer instead of having to measure out laundry detergent (and softener). It was awesome. Then you just throw it, along with your load of laundry, into the dryer.
So easy. Smells so good. Loved it!
(and NO they didn't pay me to say that=)
