I mean, for basic goods, there are laws against false advertising and selling defective goods (lemon laws in the US).
But at this level, these bastards can put a fresh coat of paint on a rust bucket and sell it as a Ferrari... and get away with it? Infuriating.
On a personal level... When I was growing up, it was goldmine of electronic components, DIY kits, etc. I visited a Dick Smith a few years ago and it was terribly disappointing... computers, televisions, phones. The DIY stuff that was a makers dream was gone. I believe a parallel in the US is what happened to RadioShack.
