Anyone know a cheap place I can get appliances and/or furniture?

Moving into a house in Houston in September and I'm looking to get some appliances soon too, a washer, dryer, and couch in particular, but also for other miscellaneous furniture. Home depot/Lowe's/Gallery furniture are all I can think of off the top of my head, so you m looking for good recommendations for those types of things. Any help is appreciated!
