I do not think it is sad at all. It is so much easier to do it now or over the next few weeks, rather than in the crush and near-mayhem that fills the shops in December. You can more easily think what people would like.
I have already bought one Christmas present. Something I saw that was ideal for someone.
I must admit to having bought the cards last January
but in mitigation, my favourite design was in the sale, so I stocked up. Fortunately I do not need to buy loads of pressies, and most people will be getting a bottle of their favourite alcohfrolic liquid and/or their favourite chocs.
I would add that my cats are very clever. They can go on-iine and order some presents for me, that they know I would like, but other people are not likely to buy for me.
