We have purchased several washers, dryers, mattresses, and stoves (for our own home and for our rental properties) on Craigslist and have been very satisfied. We found some really great deals and cheap prices on gently used appliances. The most recent was a almost-new front-loader washing machine. It helps that my husband buys them, though; if I did it on my own I'd probably buy a broken one or something, but he seems to know what to look for. So I'd check Craigslist daily. Also you can put a "Wanted" ad (it's free) on Craigslist that you are looking for those items. You probably don't want a mattress from Craigslist unless it's new and in the package, but I always see great deals at furniture stores in the scratch and dent room in the back, and there are always a lot of mattresses. You might try that! Good luck. Or the scratch and dent room at applicance stores like Hahn for a washer and dryer.
