The batik FQs at www.webfabrics.net are less expensive than many of the other stores. You can buy by the yard or by FQ. They range about $2.35-2.55 per FQ. They are about $3.00 at my LQS now. You can pick and choose the ones you want if you don't see a bundle that appeals to you.
Ebay can have some good deals too.
