This is a perfect example of why there's really no need to worry about people who list animals below market prices in the grand scheme of things.
The reality is that there are buyers out there for everyone. Some are just looking for the best prices, while others have committed to finding a particular animal and when they find it they're willing to pay a little more to acquire it.
Even with all of the low prices out there (and they've been out there for years), I'm still able to sell out of all my available animals every year ... hundreds upon hundreds of them ... no matter how they are priced.
Hope this helps.
