I picked up several of these bags from Coles in Bentleigh this evening, they were $1.29 for 700gr bag which comes to $1.84 per Kg, about 9 good size Mandarins in each bag.
they are easy to peel, sweet and juicy, ideal for the kids lunchbox
I was told that they should be available in many Victorian stores, not sure if nationwide
got some as well in sydney.. dont like them much, hard skin and some of them look a bit old.
