Most places don’t carry it. It has fairly limited distribution, mainly in a few big cities. I’ve never seen it either outside of the NYC area.
Any city with a sufficiently large Jewish population will have HFCS-free Coca Cola available at Passover.
Mexican Coke, which runner pat mentioned, is an interesting idea. I’ve seen it at supermarkets here in Chicago, but I don’t know how common it is nationwide.
Did you think I was addressing you? Sorry. This was clarification for those who may not know that kosher and kosher-for-Passover aren’t the same thing.
Note that Poundstone’s excellent book “big Secrets” exposes many secret formulaes, and there’s no insect parts (on purpose) in Coke. Nor is there any cocaine, except perhaps a few stray molecules.
even if it’s only in small amounts, can you imagine the daily volume requirement?
Costco often carries them.
In my experience you won’t find it at most supermarkets. In the Boston area, for example, it’s found in Newton and Brookline, but not necessarily in other suburbs. But if you must have it, I agree that you can find it.
I’ll never get why this is gross, but eggs are not. People eat all sorts of weird animal products and yet, it’s the mashed up insects and shellac people are all worried about. It makes no sense.
Junior Mints actually became kosher earlier this year, so presumably they’ve reformulated to a bug-free version.
Mexican Coke is sold at various places and contains sugar instead of hfcs. Costco and target are a few places that carry it.
The biblical rules on what is kosher contain a specific exception for locusts. As for honey, it is also mentioned in the bible so everyone assumes it is kosher, even though bees (and ants) are forbidden.
Just for the record, there is at least one substance that is kosher, although it is forbidden to eat the animal source.

What? You only use the missionary position? 
As I understand it, though, most rabbis are no longer confident in precisely what species of locust was allowed, and so they now consider all insects to be non-kosher.
It’s fairly easy to find Mexican coke (the drink) in Vancouver, BC
Even I wouldn’t drink 11 year old zombie Coke.
It’s also fairly easy to find Mexican coke in Vancouver
So there’s “regular” Kosher, and “Kosher for Passover”? I wasn’t aware of that.
Yup, separate.
Heaven forfend!
