MONROE-A large white banner which says, "We're hiring," now hangs over the front door of the former K-Mart building. National Liquidators, a discount retailer is moving in on a month-to-month basis, according to Monroe Building Inspector Jay Wilkens. There is still a possibility, he said, of further development by another prospective tenant but plans are still in the negotiation stage. Wilkens said the store will sell off season items, furniture but will not sell clothing. An opening date has not be announced.
