Shows limited stock available in Kmart stores. But I went to my local store (showing zero stock for click and collect online), and there was 3 on the shelves hiding amongst the Interstellar Spaceship (60430) sets. All time low for this set was $15 by The Gamesmen and Amazon back in May.

126 pieces, for ages 4+ ($0.1270 per piece)
