Settlement Rd, in the homemaker centre where Lincraft is....
Don't know about second hand, but there's a place that sells factory seconds on Cooper St Epping (or is it Campbellfield there? ). It's just before you get to the Hume bypass, on the right-hand side, can't tell you the name. There's a bedding place next door - or was, last time I was there.
Maxwell's on High St Epping, opposite Epping Plaza often has fridge specials, and the old Spotlight shop in Mill Park at The Stables is a discount/junk place at the moment. It's like a $2 shop on steroids... They have factory second fridges, we got one last week to replace our old beer fridge in the garage. They're closing down though, not sure how long they'll be there.
