I just have no clue- DH has specified NO CLOTHES 
DH and FIL both like the same kind of thing: books (getting them a Waterstones gift card each), gadget type things, Star Wars and tv programmes like Stanger Things etc. FIL is particularly into horror, DH not so much.
Over the last two years, both MIL and I have bought them tickets to things and they've said they would rather get things this year but, upon questioning, don't know what things they would like 
So any recommendations or telling me what you're getting your DH/FIL would be greatly appreciated!
