Not really an item for sale as such but thought this may be of interest to other forum users.
Tesco have reduced their internet phones to under a tenner (and they includes £5 of call credit.)
Now, the important thing is that you get another local phone number with one of these phones. That means you can have your existing BT number exclusively for business calls and your "Tesco" one for personal calls, or vice versa.
There's no line rental to pay and calls are charged on a "pay as you go basis". The phone simply plugs into a USB port on your PC. It also means that you can make/receive calls on TWO numbers at the same time.
No more embarrassing confusion as to whether it's a customer calling or a friend!
(I have no connection with tesco, by the way)
