$20 RRP at my local countdown, usually go on special at $18 or $17, sometime they do $15 but not much so I usually stock them when they hit this price because missus love prawn. I have seen them 2 for $26 last year but just once never goes that low anymore.
Now you can buy 2 for $30 online, it's the cyber Monday deals extended, I order it with the new user $30 off $100 so pretty good bargain if you consume a lots of prawn.
Already bought them, great price, loving it!
