Amy Pond items are all out of print and fairly rare. While they are not nearly as rare as earlier companions (Rose for example), they are still rare. To find these items you will need to search eBay on a regular basis and be very patient. As with any other Doctor Who costuming item, expect to pay top dollar nomatter what the retail price was.
