I've lived within 20 minutes drive of this op shop for 7 years, and I never knew it existed. Apparently it's been around for over 30 years. Down a little gravel driveway off the roundabout is St John of God Accord's Op Shop. It is one of the biggest op shops I've been in (except for those huge chain-store type ones) and it's full of surpises. Inside an old dorm house are rooms full, mostly with clothes. It's a good thing they are having a sale this week and next week - $1 a piece, for all clothes and shoes. My favourite room was the linen and craft dorm. DH's favourite was the books and music (read: vinyls) dorm. I think this may become one of my very favourite shops. Very friendly staff.
Check it out: 108-130 Diamond Creek Road, Greensborough. Open Tues-Thurs 9am-3pm.
