I guess a traditional vendor will make their own products that they are selling. The marginal cost could be pretty low, and there is no fixed price put on the hourly rate of the vendor. In that case it makes sense for the vendor to sell at any price that isn't completely insulting if they have product available. It is not dishonest because there is no fixed price in the first place. But it would be stupid to sell yourself short, and that would devalue the product and insult the buyer.
