Right now Walmart has Dial Bar Soap on rollback- $3.72 each (remember prices vary by area but this should be a ball park).
So grab this coupon for $2.00 off 2 Dial Bar soap  and get them down to $2.72 each- $.34 a bar!
That should help build up your stock pile and keep the people in your house smelling good!
And in case you doubt the power of Dial you can watch their television commercial that explains it all!
