Some other cheapish things too, such as Sensodyne toothpaste 2 for $9.95 (BIG W has them reduced to $7.30 or thereabouts, but $5 beats that! (The Sensodyne offer doesn't seem to display in the pricelist but it's in the current catalogue and available instore - perhaps there's a way to get it online too?)
Postage $5.40 but free for orders over $100 or if puchased in store.
Store locations:
Blacktown
Belconnen (ACT - yay!)
Castle Hill (Barwell)
Castle Hill (Supacenter)
Hornsby
Mona Vale
Orange
Penrith
Richmond
In store it's a great pickup, but with postage online makes it far more expensive than it is at most pharmacys (generally between $1.50 and $2.50).
