Hi -
Skype sounds like a great alternative and like I have said before I would consider it for my older relatives, but please don't divert too much from the basis of my original posting.
Be creative with your mobile plans, remember most of you in the UK are a least 5 hours away from your US loved ones so lets say you have free calls from your mobile to landlines after 6 PM then this would work well to call in the evenings with Talkster or Rebtel. The numbers they assign you are UK landline numbers.
My BF has unlimited calls to landline numbers all day everyday and trust me he doesn't pay that much for his Orange contract - he is "frugal" that way
I guess my point with this thread was for me to share how NOT to spend money on long distance and feel it has veered off that path a bit.
PS. Happy Thanksgiving tomorrow from the USA
