This is Thailand. High prices generally have nothing to do with quality and no link with manufacturing cost.
Healthy competition usually sees too high prices fall and quality maintained or improved.
I have no doubt that HHH&B is very clean and would expect nothing less. I have bought and been satisfied with the quality of products I have purchased there in the past but not always the flavour or price.This is my personal opinion.
I am fairly certain that similar operations being discussed here adhere to the same food hygiene standards and maybe even higher standards for example blast freezers, refrigerated delivery vehicles, and other expensive manufacturing and packing equipment that would maybe out of reach to smaller operations but improve quality and safety and can sometimes even reduce costs.
I and others who buy products outside Hua Hin are not just picking on any one local supplier - it is
all of them who do not meet our standards for one reason or another

As for buying online and next day delivery. At least ordering online you are sure the item is in stock and will be delivered. In my experience cheaper than local suppliers without taking into account my fuel costs.
How many times do you get to a shop only to be told the item is out of stock?
