Was just at Harris Farm at Pennant Hills and they had a bunch of good prices that I had to share.
Whole Butternut pumpkins $0.49/kg
Kumera (sweet potatoes) $0.59/kg (Big ones!)
Bucket of Avocadoes $1.99 - Each bucket has maybe 8 or 9 small avo's, but together is about 1kg for $2.
Bananas $2.00/kg (small ones)
Buk Choy 4 for $2.00 (but charged individually at 50c each)
White Raddish 3/$3.00 (but charged individually at $1.00 each)
Other specials - check your local!
+1 because pumpkin and sweet potato cheap. Others are always that price in Harris farm
