It's $5 for a 20kg bag of pebbles, they had White (kinda a dirty white…), Black and a dirty yellow stone colour. Good for gardens beds, pet rocks, etc…
the staff said the last price before that was $10 but its usually more than that.
I've bought similar pebbles before and they're usually $20+ for a 20kg bag.
They're sitting on pallets outside the special orders entrance, there was 10+ bags left of each type.
Not sure if this is at other bunnings, but could be store specific.
This deal rocks!
