3 versions of the thai style chilli sauce but i only come across the smallest & medium version locally. The biggest bottle is in supermarkets in Malaysia. Though the medium version is available locally it is not common. I bought the medium & bigger bottles from malaysia & already the medium bottle is cheaper & yet more quantity than its S'pore smallest bottle.
All 3 bottles originate from Malaysia in same factory. Is just packaged differently.
355g RM2.59 $1.07

300g per gram price $0.00383
355g per gram price $0.00301
520g per gram price $0.00236
Going by unit price the biggest bottle sold in malaysian market is the best value for $$.
