Been offered it many times in the past.
Usually in conjunction with a phone directory company.
The usual spiel – "there were 300 new businesses in your area last year, and over 150 moved premises – we can exclusively give you all of the leads if you sign up today for £400 – that’s under a £1 a lead."
If this was REALLY so, why do they have such trouble selling the deal – surely the bigger sign companies would have it sewn up every year and everybody else would be out of business.
Get a lot of the web ranking deals too – just laugh at them.
