hellocandy,
I have four spare pieces and can mail to you. Just pm me your mailing address.
Free of charge - I got from a friend the Medela double electric before my baby girl was born, but it was out of order before my first use. It was bought 9 years ago, so of course no warranty. I just keep the useful parts and the bottles.
Let me know if you want them la.
