Suppose Top Shelf Vodka ordinarily costs $6 (actual retail prices may vary). If you go out and buy a round of drinks for yourself and three friends, that would come to $24, plus tip.* On Cheap Top Shelf Vodka Night™, if prices have been lowered to $4 (that's cheap!), the same round would only cost $16 plus tip. You can take the $8 you would have spent and put it in your pocket. Order another round, tip your bartender,* and put another $8 in your pocket. You've saved $16 cash! Depending on the length of your stay, you could take home a substantial amount of CASH MONEY that you otherwise would not have had!

*Always tip your bartender, it's Good Karma.
