You need to be TOP, to get anything from that.
The higher up the list the more chance your name will be read out.
I had an example of it on the phone,m where by the sales operator phoned another one in the call centre, asking for a window cleaner (residential or commercial in a specific area) they will read out the top 1 or 2 and ask if you want them to continue with the list - whats the point when you have 2 numbers?? the rest are then obsolete.
Least on ther website you might scroll down a bit further, and to be honest who really uses telephone directories if they can use a computer? or the book?
IMO waste of money, but dont take my word for it try to call up yourself to see how it works, and then ask the sales rep how much it is to be ranked top in your area!
