Every year, but by choice here. Husband and I are saving up for land, and we don't really like "stuff" and being tied to possessions. Sometimes we'll do presents on a short budget (usually not items, but things like play tickets), sometimes a little car trip with the dog, sometimes we make a really special meal, etc. We've also told relatives that we don't expect gifts. Oh, and sometimes we'll do a tree, but usually we'll buy a neat looking plant for our house from a local plant shop, and decorate that. We've had Christmas succulents and mings before. XD. We've skipped trees before too though. Just kind of go with the flow of what we feel like. Can't say I've ever had a stressful holiday since doing things this way.
