There is a new $1/1 EcoTools Products coupon that you can use at Target to get the EcoTools bath sponges for nearly FREE!
EcoTool bath sponge – $1.04
$1/1 EcoTools Products
Final Price = $0.04
Last time I checked, my Target did not sell the EcoTools brand products so your mileage may vary. There are reports that Walmart also sells these for $0.87 which would make them FREE there too.
