Masters is a premium products, high margin business competing against Bunnings which is the opposite - a totally different beast to their lower margin, high volume supermarkets. One could see Masters was doomed from the beginning.
Having worked sausage sizzles at both Bunnings and Masters I can corroborate this. Masters is empty in comparison.
Closer to topic though, when buying a new TV last week my wife and I didn't even consider Dick Smith. They can't really compete with Harvey Norman, Retravision, Good Guys or JB Hi Fi.
Meanwhile, Jaycar and Altronics have slotted nicely into the hobby electronics market that used to be Dick Smith's domain.
