Thank you, Prudence.
I agree that most trade does pass though the city stalls, but I doubt you will want to consistantly want to undercut the Animist Guild's prices for herbs.
The guild shop usually has 6 of most herbs in stock, and prices are subject to seasonal variation. This is basically a function of how well the herbs are growing compared with demand.
Those who would purchase herbs for later consumption are reminded that they will need to purchase and learn to use a herb pouch (Scholarship Skill applies).
Herb pouches, not being herbs, are not usually for sale from the shop and customers are advised to purchase them from such city stall as suits their nationality or trade aliegance.
