These are Dan's Member Deals so I expect they'll expire at the end of the month. Talisker is my favourite Scotch with a lovely coastal tang to it and some solid smoke & peat that aren't as pronounced as you get with the Islay monsters. It's a really good price now, at least $20 less than most places.
Bushmill's Blackbush is an okay Irish whiskey and may suit some people's tastes, $10 off is a normal discount and doesn't represent the same value as the Talisker.
I've never had talisker before but enn meaning too.
I vowed to stop buying new drinks but if it's a deal, how can you resist?
