The sheep will all buy the first product she brings out it's the same with all the Huns. The thing is they think they can keep selling that amount consistently but it's trying to keep the sales up to that level with each product she brings out that she needs to be worried about or she will find herself with a house full of stock she can't shift. She might find she made a big mistake by not just bringing out a complete set as her one and only product. Better to have one of something that sells well than a variety that are slow selling.
