Past few years have got big coffee selection boxes (Whittards) for DB, coffee mug with espresso coffee in for him and also for his BIL.
Jumpers and sweatshirts (Fatface is brother's fave) from places like H&M, checked warm shirts too, try Gap etc for all. Socks in VW beetle van mug got from Fatface last year.
Got an automatic (on a spring?) credit card holder for DB for his birthday this year, gadget type but he saw it and really wanted it.
This year so far got some posh hair putty/wax from my hairdressers (for men) which he will like.
Other good presents for DB's FIL who's paraplegic and has cerebral palsy have been vouchers for Royal Opera House (he loves going there), one year was a really nice China mug from Whittard with small good espresso coffee bag, nice mint chocolate (Lindt?) wrapped in cellophane he really liked that. Got self stirring mug (for disability) but also for fun factor.
Also check what they like - DB's FIL is member of Bath Rugby Club so their website has excellent ideas.
For boyfriends in past has been nice (Joseph etc) shirts, cuff links, wallets, Red letter days out etc.
Stepdad shirts, ties, aftershave. Conditioner he uses in hair (Paul Mitchell).
