Adam-
Based on your post I went and joined Costco--the closest one to me is in Clifton, NJ. I was HUGELY disappointed to find there was NO MEXICAN COCA-COLA. I spoke to the warehouse manager who had no clue what I was talking about, but agreed to do a regional check and found that only the Costco's in Texas carried Coca-Cola de Mexicao. I am enormously disappointed. I see you are in NYC, so what Costco were you referencing? Where did you see Mexican Coca-Cola? And does anyone know where in Northern NJ I can purchase it? (After a visit to Mexico I have become addicted to the stuff. Other than a restaurant here and there a few bottles purchased on the web, I've had to go without. I'd love to buy a case. HELP!!!)

Even better than Mexican Coke? BERMUDIAN COKE. I'm fortunate enough to be a dual-national and grew up tasting the difference between US and Bermuda coke. Now that I've had a chance to try Mexican coke (I'm in Mexico now), I can tell you Bermudian coke is even crisper, and less harsh than Mexican. In Bermuda, you can also find Sprite made with real sugar. I've even gone so far as to bring back Coke syrup with me and carbonate it with a tabletop carbonator! The people in customs tell me it's not that uncommon to bring a Coke syrup-pack across.

MaryResta, they've been selling it at the Costco's in Colorado since early this summer...we are awfully close to Texas, but from the posts above, I am pretty sure they are selling it at more locations. Costco employees are usually very good, but I think the one you worked with didn't give you the complete story. I'd just request it with one of their forms and get your friends to do the same. It just might show up at your local warehouse. Also, in Colorado I've found it at Mexican grocery stores, not sure if you have those in NJ, but it might be worth a try. It is just very spendy outside of Costco.
