I dont know where the OP is located but Coke made in Mexico is very easy to obtain in Hispanic neighborhood groceries and many supermarkets in Dallas, Austin, San Antonio and i assume many other locations. Its really good.
Hope it ok to put this in this COKE thread....but... the DR. PEPPER that's prdocued in Dublin (Texas, not Ireland) is also made with SUGAR. Little harder to find but Central Market and a few others usually have it in Dallas. (If someone already pointed this out...mea culpa...I did not read all of the posts in the thread).
