Some Lowe’s stores have the Clorox Green Works laundry soap priced as low as $1.22 each for a 30 load bottle. It’s not available at all stores but may be worth a look to see if a store near you has it. This price is only available with in store pick up.
I even found the Method Laundry soap for $1.40 each for a 25 load bottle! Again these aren’t available at this price in all areas but it’s definitely worth a look!
Go here to see if these are marked down in your area!
