Anna Hibiscus audio books?

UPDATE: You can get 1 month free to audible.com as a new subscriber, then get 2 free audiobooks and buy any others that you want at a discount. The audio files that you download are yours to keep, and they work with iTunes. So I bought all 4 Anna Hibiscus audio books for $12.72!

Does anyone know where to buy the Anna Hibiscus audio books? We borrowed them from our library and LOVE them! The narrator's accent and different voices for the characters add a wonderful extra layer to the books! But we can't find them for sale to individuals - only libraries. Anyone know of any place to buy them personally? Or have copies they are willing to sell?

I had no idea that such a thing existed! Looks like audible.com has them.

We love the Anna Hibiscus books!! I will have to look for the audio!

Thanks! I do see them on audible.com but I think you can only access it if you have a monthly subscription.
