This 90 minute sit-down whisky tasting experience by World of Whisky in Double Bay, Sydney was previously offered by Groupon for the same price, but now LivingSocial seems to be the only place where you can get a voucher for this experience.
The original price is $60 per person, for which you would only have to pay $30 through LivingSocial (or $59 for two). During this 90 minute experience you can try six whiskies and it also includes snacks, with tasting times available on Thursdays at 6.30pm and Sundays at 3pm.
RedBalloon is another site who seems to have World of Whisky vouchers, but they're selling the Whisky and Cheese Experience for the full price, which is exactly the same as World of Whisky is charging you if you book through their site ($99).
This would make a great gift for someone I know, so I thought there might be others interested in this offer as well now that you can get it at 50% off. :)
