get the 500 minute talk/text/web
59.99
get skype account.
i also bought a skype number which if you buy a 12 month subscription to service you get 15% off service and you get the skype number 50% off.
so thats another 60(per year) which adds 5 bucks a month(averaged)

so..
59.99(68.72 after tax) + 5(no tax) = 73.72 a month.
also this is prepaid, so no contract.
