It varies for me. Over last few years I've spent £100's on Yellow pages, yell, local newspapers, church mags, leaflets etc.
However these days I'm more cautious as to what type of advertising I'm going to spend my hard earned cash on.
At moment I have leaflets ( 10,000 per year = £90) Local church mag =£180 per year for 12 issues. That's about it really. Though I do get a few peeps looking at my van signs and then approaching me about potential work.
