I have no landline (cos i hate BT) so i have to call all 0845 and 0870 numbers from my mobile. Now i use this site www.18185.co.uk to get big reductions on the price - per minute - of these calls. This is just the site i use, as recommended on the Which? websit, but i'm guessing there must be others out there. It's a faff we shouldn't ...
