I've come across several Lindt outlet stores around Europe, and had great success buying their bulk bags of chocs.
They were great for filling a wooden advent calendar last year. I also got some proper hot choc chocolate, if that makes sense. It was grated, and made the most excellent hot choc, and also topping for brownies etc.
Ooooh just 8 weeks or so until they turn on the lights at the Lindt factory here, just outside Zurich. The whole building is lit up with seasonal scenes. Sooo lovely.
