It's pretty cheap. Mix it with something to make a drink.
The first time I was in Mexico I asked a bartender how Mexicans drink tequila, he told me that the two popular preparations were a Paloma, or a shot with a chaser of spicy tomato juice (called sangrita). However in Mexico they sip the shot, they don't gulp it.
Paloma: a shot of tequila, 8 oz of grapefruit soda (fresca works fine, jarritos is better, grapefruit juice, club soda, and simple syrup is best), a dash of lime juice, serve in a salt-rimmed glass with a garnish of lime or grapefruit.
I've heard it said that a Paloma is wha Mexicans drink. A margarita is what Americans drink when they come to Mexico.
