It was very similar to Ethan's work, it was the same machines that controlled the quality and the level of the magic herbs and magic pills bought in the store, and the price was a unique price, fixed by the highest authorities of Astoria so that anywhere in Astoria the prices were the same.
This was also the same reason why Ethan had advised Cassy to sell her magic pills at auctions, because the rate of impurities she could remove from magic pills was really out of the ordinary and the prices set by these authorities did not correspond to the quality of her magic pills.
The customers, once their magic herbs and magic pills were checked, received a summary of their purchases which served as a guarantee of quality and the price was not negotiable.
