Few sprint questions

[nevergonnauseth]

With my UPS discount I can get a hero for like 70 bucks and unlimited everything and 450 minutes for like 54.99 a month.

They have that free calls to home service, could i set my girlfriends home phone as my home phone number? she's about the only one who calls me who doesnt have a cell

Is there anyway to estimate the amount of taxes?

and also can i start a new line without a contract? no cell phone carrier can hold me down, im the wind baby!
