I'm going through a stable sale. All of my adult females will be pregnant, and some of my ponies are for free. :D
ETA: If you see a Pony that you want but is not for sale, we might be able to work something out, but please respect that some ponies are out of the question for selling. :)
ETA2: Most are gone, but still a bunch left! I have ponies in both stables and my nursery. All ponies are 500 PG or less!
