Trying to save the pennies doesn't have to mean relinquishing the luxuries. Instead of going out why not make the cocktails yourself.
Try one of my favourites, the Cosmopolitan.
Two Measures of Vodka
One Measure of Cointreau
One Measure of Cranberry Juice
Half Measure of Lime Juice
Shake up with crushed ice and serve in a martini glass garnished with an orange peel or a wedge of lime on the rim.
