I've been asking around. Evidently there was a toy store in a suburb that only sold Playmobil, but it went out of business a year or two ago.
My secret fantasy is to find an out-of-the-way, dusty old toystore in a shabby part of town that has a lot of old stock on hand. Since Playmobil (like Lego) is an expensive toy for local folks to purchase, I would imagine that the stock moves verrrrrrry slowwwwwly.
