Bunnings is not bad as long you know what kind of stuff to by there, way better than failed Masters.

I look for commercial suppliers near me. I recently needed 6 bolts - got them at a local supplier for less than the price of one at Bunnings. Most places are happy to sell small quantities (some require cash for non account holders).

If I’m only planing to use once or twice I’ll see if my tool library has.

Otherwise Sydney tools / total tools just have better quality stuff, especially on consumables. Eg multitool bits from Bunnings are a waste of money.
