My mom works for a company which gives her a 30% discount and free unlimited data. So its 50 dollars unlimited minutes and such, plus 2 lines (Mine and my dads) for 10 bucks each. So thats 70. Plus her international plan and my texting. So the total is 80-90$. Sometimes we get charged for little random stuff.
My wife and I pay 145.45 a month for 550min, data for my bold and her iphone, family unlimited texting, and insurance for my phone. This is after taxes and 20% off my line for having a premier account.
