Dick Smith is closing up to 100 stores around the country, which means you can find some interesting one-off bargains if your local outlet is shutting down. But don't head there trying to get catalogue bargains.
Dick Smith's own site makes it clear that closing-down stores won't include items that are on sale at its regular branches:
Some of our stores are in the process of closing. These stores will not be participating in our regular catalogue promotions. The closing stores will be running fantastic closing down discounts across the entire store until all stock is cleared.
If your local store is shutting but you're after a current catalogue special, hitting the web site would seem to be your best bet.
