I recently sold my Bugaboo Bee on ebay. The buyer arranged a courier collection (DHL) and I boxed it up ready for collection. The buyer has now informed me that one of the bars has snapped in transit and another of the plastic tracks has bent. The pram still has a few months left on its warranty. I'm not sure if she took out the courier company's insurance. What should I do? Who is liable? All suggestions welcome!
