We will be headed to Cancun in just under a week and are planning our souvenir shopping. Normally (and our kids enjoy this) we get shot glasses from the location we're visiting and something that is culturally or traditionally representative of the area we visit; we're thinking tequila and/or vanilla. Vanilla is easy as it isn't restricted from a customs perspective, tequila is a bit more of a challenge as we're only allowed to bring back "so much" alcohol. Does anyone know what the standard bottle sizes are in Mexico? We need to get 5 - 6 bottles of tequila and remain under our customs limited amount and so are hoping that there is a size that is equivalent to our mickey (375 ml). Any feedback is appreciated.
