I'm with you Hoyks, I think Bunnings are stocking more and more cheap cr*p, or huge amounts of the same stuff without much variety, and heaven help you if you want assistance. Masters does/did seem to have brands that Bunnings doesn't, and I shop at both to give myself the choice of brands.
I will certainly be sad to see them go, not only will great brands suffer less exposure, but having a giant company monopolise the hardware market won't be a good thing. "We'll beat any price by 10%" is going to be quite difficult to get if there are fewer stores in competition, which was obviously their aggressive strategy.
