For me, most of my friends have known what I've wanted for almost as long as I have, so they get the meaning behind it (not exactly rocket science, I have a Griffin on my arm, give you 3 guesses what my surname is). It's only ever strangers that ask, and like you guys it's most often the "how much & what does it mean" combo. I round down with the price, and love seeing their faces when they realise how much a good quality, relatively large tattoo costs. I never explain the full meaning but tend to give a rough outline, just enough for the person asking to be satisfied.
