Hope you decide to sign up and join the insanity, that way we'll know where you are. It will help to know the area you are in, that way we can direct you to a source close to you unless you live in BFE. Then you are on your own.
I picked up a couple of mops, that are similar to the ones you are asking about, at the local supermarket. They were only a couple of bucks. You could probablly find them at Wally World.
