Or, your FIL for that matter?
I have no idea what to get for either!
My dad's the kinda fella who buys himself anything he wants so doesn't really need or want anything IYSWIM. Last year he got a scarf! Which he probably wasn't impressed with tbh but I never get much to work with frim either him or my sister (we only see them every couple of months or so!)
& my FIL is happy with anything at all. So far over the past 4 years we've been together he's had a beer selection box, dvd's, pen & diary and liquer chocs.
I'm stumped for both this year because I'd like to give them something a little better (although I'm not sure that's the right word), now we're in a better financial position.
