Ecotools is offering a $1.00 coupon right now when you register for the emails. The coupon should come in 24 hours.
As of posting it is $1 off but that might change to $1/2 at any time.
The little bath puff things are $1.04 at Target- so as low as $.04 after coupon.
I saw these once at Walmart for $1.00 but that was during the holidays. Worth a look if you like these things!
You need to register for the Ecotools emails and then wait for your coupon to come.
