KitKat Dark 70% Cocoa Chocolate Block 170g $1.10 (Was $5.50) ($0 C&C/ in-Store) @ BIG W (Select Stores)
Big W are clearing this and there actually seems to be a bit of stock around. I did try a few stores in different states and it was still the clearance price. I believe it's pick up only.
Hope it's at your local!
Edit: Unfortunately it looks like it's not $1.10 everywhere. Usual hijinks from BigW. (Seems like VIC and SA aren't invited to the party just yet. Hopefully they follow the rest of the states and reduce their clearance price again)
Edit 2: I have put these links in the forums but I'll put them here:
Food
and Drink clearance items in "your area".(bigw.com.au)
Food and Drink clearance items Australia
Wide(bigw.com.au)
I don't know how they judge something to be in "your area". It does seem to cast a pretty wide net.
Also, I don't why they keep some products on page that 2nd link points to. Is it because there is one lonely packet somewhere in Emerald? For some products I can't seem to find any anywhere, but it still shows up on that page.
