Got the $50 voucher, paid $8 on site to become a VIP to sample both shine and "bourbon". Don't recommend the "bourbon" as 3 of the 5 options are flavored whiskey, and one is a cocktail.
Using the voucher was straightforward. I purchased 2 shine bottles and after the $50 voucher, I paid the balance remaining of $7.
*Had to give 5 stars for food, even though I didn't see food to purchase
