Best phone card deals

[Trespassers William]

On the undercovertourist website they have $20 phone cards which give 222 minutes calltime back to the UK. Has anyone come across a better deal?

we usually get our phone cards from walmart, and i'm sure even though they say that you get so many minutes its actually less, could be that they take minutes off for the connection to uk. don't quote me on this though!

I usually get my card from 7 eleven and they seem to last a long time for the $10

We've tried quite a few different ones and the 7-eleven came out way ahead of all the others (even WalMart!), but I can't remember any figures offhand.

The undercovertourist one sounds pretty good though
