Margarita King is yet another pre-mixed cocktail

I think I understand the premise behind cocktails that come pre-mixed in the bottle which you just chill, shake, and pour right into your glass. It's for convenience, right? But I still can't understand why convenience would win out over the taste factor when mixing a cocktails is so easy to do yourself. I guess with a margarita, though, there can be an argument for something like this new produtc, Margarita King - margarita in a bottle made with double distilled blue agave Eapolon tequila, orange liqueur, and lemon juice - because a lot of people do, in fact, use a pre-made "margarita mix" anyway.

Here are a fwe resources for making margaritas from scratch:
