This is a rather small kiosk with a very limited supply.
Due to probably low turnover, be careful with the expiry dates!
I was unlucky enough to pull a due dated bag of crisps! I realized this when at home and went back. The girl behind the desk was very accommodating and got me a new bag (with a short date though). She explained to me that they got bad dates from the wholesale (which I can understand, since they probably buy from the low price wholesales...).
Any way, the prices here are the same if not lower than at next block Seven-11. read more
