^ KT ... they have been in Australia for many months now ... and I've quality tested many 4 pacs of them
They retail for $15 for 4 x 500ml cans ... about the same price as advertised in your post.
They have a heavy alcohol taste, not bad, but strong.
The down side is that I sometimes had a restless sleep after having a couple of them.
Certainly worth a 'try for yourself' experiment.
