Can anyone explain the 'old parts refund system' this shop offers?
I'm a bit confused as to what the final prices will be

New wbx heads are the cheapest I've seen online, but I'll need to ship my old heads to Germany.

It's the price of the parts plus a 200 euro deposit for your old parts.
When he gets your old parts the 200 is automagically refunded.
