How much do Pineapple green cheek conures cost?

It depends on where you go. If you go to a pet store aka Petco you're going to pay $500 (I was just at one yesterday and the price tag was for a pineApple for $499) If you do your research and find a breeder you can often find them much cheaper (I've seen them for $150-$200) and they're often socialized much better in most cases. You never know how long a pet store bird has been stuck in a cage with no attention.
