Up to 50% offMEGA Sale – EVERYTHING must go. Really.
Our warehouse in Hamburg-Barmbek has suffered serious roof damage! The situation is serious: the roof and warehouse ceiling need extensive repairs as soon as possible. To do this, the entire warehouse must be cleared at short notice. For us, this means: we have to clear the warehouse in the shortest possible time. EVERYTHING MUST GO! For you, this means: from October onwards, there will be restrictions on dispatch. But before that, you can benefit hugely. You’ll get 20–50% off items available for IMMEDIATE DELIVERY. It’s a win-win: an empty warehouse moves faster – and you can make real savings. Unfortunately, this clearance sale isn’t a marketing gimmick like those run by mattress or carpet retailers. It’s the harsh reality. The next few weeks will be tough for us – it would be great if you could support us with your understanding, patience and plenty of bulk buying!
