Actually it can't. Doses over 3g (12 pills) tend to be fatal so a big bottle at the grocery store would be a bad idea.
I bought some. My experience - Bali - no one had any. Singapore - rare, need a persceiption. UK can get from online pharmacists by saying you are going to a malarial area. (£13 for 20 tabs) which is what I did. India it's about 1 or 2p/tab but they are not officially allowed to ship overseas. I got quoted $90 to ship 600 tabs overseas.
