It's quite expensive i think, $35 for 7 Schooners
It's about $38 for the NEw, TEDS, Superdry etc and for that you get 6.4L - a schooner is about 425ml which works out to be about 15 schooners, or $2.50 per schooner. Even cheaper if you want to go XXXX.
A few bucks cheaper than buying a schooner at the pub, and there is also the novelty factor of having beer on tap at home.
A schooner is also bigger than the average bottle of beer which is worth keeping in mind as many people make comparisons between the tap king and a case of beer.
