T.F.
My mom and stepdad have everything. They are retired so they don't really need knick-knacks, etc.
I did find a digital picture frame that is very nice and that is what I am getting them this year. You can find some reasonable ones and some super duper ones.
Last year, I gave them a towel warmer for their bathroom and they have expressed many times how nice that is when they get out of the shower or bath.
Hope that helps!
