I loved this post on the BBC website. It relates to Christmas 2012 but I think it says a lot. This factory town in China the BBC visited makes half of the US and European imports of Christmas decorations and in 2012 the orders for Christmas trees were for smaller, thinner trees than previously. This is believed to be a result of the global recession and I guess that these trees are significantly cheaper to make and transport. Interestingly the market for Christmas decorations is growing in China itself despite the country being athiest - they like the tradition. Here is a link to the BBC news piece: http://www.bbc.co.uk/news/business-20797921
Of couse you don't have to buy a tree or grand decorations. Christmas welcome lights or a nativity scene are equally festive and will last for years.
