Was on my yearly Officeworks trip and found this book in a pack of 4 hiding under the table display. Checked online for the price but only found the single book for $2.28. Went to the checkout and found out it was only $2.25 for a pack of 4! Great for poor uni students like me.
Bought at Officeworks Liverpool. Not sure if other stores have this.
Anyway here's my receipt because I thought it was too good to be true http://i.imgur.com/pjqTmeo.jpg
Hmm im guessing they only scanned one barcode which was the sku for just one book.
edit:never mind the description says otherwise QX-PK4 , ill have to get one or two also
thanks good bargain.
