Might not be as good a deal as the $7 3D offer from Big W a few months ago, but still a good deal.
Walked into my local Big W (Nambour) at lunch time today, noticed a stack of Man of Steel blu rays on a clearance section, with a bunch of other dvd's, the attendant said they had a heap to clear for $5. Scanned at the checkout for $5.
Sorry about the receipt image, didn't print that well at checkout, but rest assured it is $5. And my kids love the cape!
Stil, it's only five bucks.
