Staples just released a super rare printable coupon valid for $10 off a $10+ Swiffer products purchase, valid through November 9th. This could make for something free or at least super cheap!

UPDATE: Apparently this coupon is supposed to be a $3 off $10 coupon, so will only take off $3. A manager will have to do an override if they will honor it as a $10 coupon.
