The PM bars are just lumps, so don't quite know why the others are not more attractive. But they are also usually the best price, given the lack of adornment, so I guess that figures into the equation.
Yeah they're not the most attractive bars but if I lived in Aus I'd probably stack them sue to price and liquidity. It really depends on where you live. Same goes for just about anything else in life, people buy what they know.
