Ofcourse!!! Well something I used to do when I was younger and living with my X. Buy non-perishable things you need. And wrap them up with spare warping paper. And mark it all from Santa. I would hide it till Xmas night an would sneak out and place the gifts. She knew it was from me, But I had a friend write on the labels so it was hard for her to prove.
And the gifts where things like hair ties, or a new keyboard, toilet paper, etc..... It made it fun a lot of fun. And I went from 1-3 gifts for her to 10+ easily.
