I’ve got some very good discounts on tools from mitre10 by using their guarantee.
Bunnings usually have the same items (in my case DeWalt tools, but any international brand should work) for a few cents less: instant 15% discount. Occasionally the difference is several % before the price match.
It’s worth exploiting it when you can: they’re exploiting you anyways…
I’ve found that place makers tends to be a bit more expensive.
Most of the alternative local stores just don’t keep the stock on hand or are advertising GST exclusive pricing for professionals.
