I'm am now convinced now that you need to be right at the front of the CC section or right at the back.
If you end up in the middle then it wont work, 1 CC near me said it always worked when he was at the back, this year this didn't happen and he noticed a big difference at the lack of calls. I was right in the middle this year and it was a total flop, where as in previous years when at the front it did bring in a bit more work.
You also need a good advert too, but that's stating the obvious!
