Talked briefly on the phone with the Parts Dept in the US today. Their next expected parts delivery from Germany is in March. If you've ordered anything since the fall and it was out of stock it still will be until March some time.
I'm going to try sending an email order this time and see how that goes, it's been a while. The rep said to send to service@playmobilusa.com - that's new, last time it was through Playmobil.com and then rerouted from there.
She said to include name, address, phone number. There will be an email response, and they have to call you to confirm the total before they can charge you.
