No outdoor summer party is complete without a margarita in your hand, preferably with a couple more on standby. Master of Mixes created the Big Bucket Margarita Mixer to guarantee that you have cocktails for all of your guests. The giant bucket boasts a bag filled with the margarita mix. Add a 750ml of your favorite tequila to the mix, pop it in the fridge or fill it with ice, and you're ready to fill your cup using the convenient nozzle. So easy, it's pretty impossible to mess it up.
