Over the last few years I have not done bad from BT Phone Book, nor the Thomsons.
But this last 12 months - gone right down.
I too dont mind getting a £ back for a £ put in - after all you should get repeat and referrals.
But I dont think I will be going with them the next time, and once you are with them if you want to reduce the size the £ figure they come up with makes it such a bad deal to do so.
Yell.com may be a goer - still get a few clients saying they got me from Yell.com, directory.......... mmmmmmm.. better then the other 2 but not brill.
