If you want to call overseas (relatives, friends, planning your route 66 holiday) you’ll know how much international calls cost. I was watching the (not quite unbearable) ONE Show on BBC One last week, and came across this method of making your calls cheaper.
http://www.telediscount.co.uk/ for example, is an 0845 ‘Proxy’ service. You dial a lo-call rate (3,2,1p per minute depending on the time of day and the service provider) and then once you are connected you enter the number of the person you want to call.
Of course, this is negated by using VOIP – but apparently the line quality is excellent and 1ppm is certainly a whole lot better than the standard international call rate in the UK. Calling a US Cell phone for 1p is great – here from a landline to a UK mobile phone is about 14p+ at the very least.
