I think in all homes, there is a bottle of soy sauce, but I also learned the time they bought it, it was in a retail style. It is packed in a strong plastic bag of enough size according to the amount either I kilogram or two. Why is this so, it's simply because there are buyers who do not buy in big bottles. It is also heavy. For small stores, there are displays of retailed soy sauce affordable for everyone. What about you, do you consider this style profitable?
