Depends how much you like and how well you know the person you're buying for. If I found myself buying for someone I liked, I would take the effort to find something that really suited them.
I remember one year, a good friend - single, in her twenties, was bought a present by a well-meaning and kindly bachelor in his sixties - a tin of biscuits! Although we weren't supposed to know who was buying for who, we usually managed to find out, and because some of the girls had an inkling this might happen, they bought her an Anne Summers chocolate willy for a laugh.
The following year, I was the one who drew her name from the hat. She worked out that her present was my responsibility and said, "I don't care what you get, but just promise me it won't be a chocolate c*ock and a box of biscuits".
So, I bought her a big pair of fluffy slippers in the shape of cockerals, and packed them up inside a supermarket biscuit carton with a packet of chocolate digestives - so she got chocolate biscuits and a box of c*cks! She loved it.
