Went in today (Sunday)… Saw the Fruit & Nut blocks for $1.50 a block and took a snap with the mobile phone (sorry for quality).
All the other You'll Love Coles brand blocks (Mint, Milk Chocolate, Dark) Were on special also for $2 a block… same 250g size… so Fruit & Nut is the best bargain of the lot.
I live in Victoria - Rural area… I wouldn't have a clue if its available everywhere, so maybe look out for it next time your in Coles.
If you provide a use by date on the blocks might be a sign as to if its just a one store or state/nation wide
