Entertainment book members can purchase a case (6) of Yellowglen Spritz Chilled White for $25 delivered ($4.17 each). I've got the Sydney book. Not sure if this is available to all Entertainment book members nationally. I think the wine is shipped from Victoria. That is 72% off RRP apparently. Dan Murphys is selling these for $47.40 a case http://danmurphys.com.au/product/DM_710123/.
