This is a simple one. It’s also free. Use newspaper or old magazines instead of wrapping paper, ideally ones you already own.
It’s something I’ve been doing for a while and dependent on the date of your paper, can make you look very well organised. You can also pick sheets with relevant images etc. and they are a lot more fun to personalise I find then your usual paper.
This alternative is for all ‘wrapping’ occasions, not just for christmas.
