I know of a rescue near where I live, and they sell their horses anywhere between like 600-2000, but its all based on the horse, and the amount of effort and time that they've put into it, and age ect. And all the horses that are rideable are evaluated, worked on until they are nice and safe under saddle, and they do keep some of the unadoptable horses, pasture puffs, horses that have too many issues to safely adopt out, and they all come with a guarantee that if you don't get along with the horse, you can always bring it back and find another for free. What I think is funny is that on the home page they state that they rescue these horses so they don't go to auction, and yet they are going to auction. I think that they really should get some training on these horses, at least evaluate them, halter break them and determine what they would be able to do. I think that is ridiculous to try and sell for profit, just like another rescue I've seen ads for that only take in rideable horses, because they have to be able to adopt them out. If you are a rescue, you should be able to take in any horse, rideable or not, and find homes for them, knowing that some of them are going to go for nothing, and none of them are going to go for much over 2k for a well trained medium age horse that is registered. I don't think that it does any good to be angry about it though. If it bothers you enough, you should try and do something about it instead. Help to give these horses a better chance at a good home, expose those rescues that really are in it to try and make a profit ect. There's a reason they are called non profit, and if they are making a serious profit, or trying to make a serious profit, I think that there are probably some legal things that can be done about it, but someone will have to bring it to the right person's attention.
