It's a problem I've faced on several sites. Conversion optimization is the way to go, IMO - including A/B split testing. Sometimes you can double conversions with the same traffic, if you get a good tweak on the page. And when you co A/B testing in a disciplined way it can be astonishing what actually makes a difference.
