Swiffer Cloths At Dollar Store

I bought a Swiffer regular floor sweeper when they first came out. It worked great and picked up even more dirt after I vacuumed. When I saw the price of the clothlike refills, I decided not to pay the high price. So when I was at the Dollar store, I saw a package of Swiffer like cloths. I got 20 cloths in the package for a dollar. When I got home I dusted the floor. I took off the cloth and was going to throw it in the trash when I noticed the other side was clean. So now I turn the cloth over and get double duty.
