This might be worth a try for some. Frankland Estate Isolation Ridge Shiraz is showing at $17.30 per bottle at some DM stores.
But if you add 6 to your cart the price doubles...
$17.30 in any six
$207.60 per case of 6
$24.78 per bottle
The trick is to add 5 and then add 1 bottle of a different wine you want to buy.
The vintage delivered will probably be 2017 or 2015, I've had both in 3 deliveries, not one 2016.
This was originally listed as
$17.30 in any six
$207.60 per case of 12
$24.78 per bottle
But when you ordered a case only a 6-pack arrived. One of my subscribers was offered a refund instead of the extra 6, I managed to get the extra 6 by showing a printout of the listing with the dozen price.
