Are you looking for clothing or other stuff? There is a place in Wanaque (or is it Haskell there) - I think it's called the Storage Chest (I couldn't find a listing for it, but I drove past it yesterday). It's on Ringwood Ave, and it's almost directly across from the Wanaque Post office, and the CVS. They have a lot of used household stuff there, sometimes furniture, etc. Sometimes it's a disaster, sometimes more organized, but sometimes digging for the stuff is half the fun, right?
Update - it's called the Treasure Chest, it's kitty-korner across from the CVS.
