I've had some great bargains from Ikea, but notice that the Eastern States do not seem to get the same deal.
WA and SA seem to be a separate company owning the franchise.
e.g. Tundra laminate flooring - excellent stuff at $13/m², beating most of the cheapest Chinese versions at Bunnings etc.
But if you live in NSW the same product is $19/m²!
Looking at a few things I bought today, a pair of kitchen cupboard hinges $5 in the West, $10 in the east.
What else is good at Ikea? White powder-coated steel bunk beds, very solid. A bargain at $129 the set, but $199 in the East.
Oh well, you guys have Aldi.
To compare the two, switch between 'au' and 'aa' in the URL (just after ikea.com/).
edit: works both ways: pendant lamp $99 east, $139 West. This are friggin' big differences. I dread to think what their markup is.

Eastern States have cheaper deals too.
I actually bought a small bathroom cabinet at the Melbourne Ikea and flew it home with me.. extra baggage cost plus taxi from city to Ikea and back again and I was still better off than the nearest equivalent that the SA store could offer me!
