somebody check my math here.

STRAIGHT TALK PLAN

family of 3 with 3 smart phones.

a phone will normally last me about a year and a half.

smart phone $600 each x 3 =$1,800

per phone per month $50 x 3 = $150

18 months @ $150 per month = $2,700

3 phones for 18 months = $1,800 + $2,700 = $4,500

---------------------------------------------------
VERIZON CONTRACT

I currently pay $230 per month for 3 smart phones and 1 dumb phone. $230 x 18 months = $4,140 + phone cost.

yesterday I got a new I-phone 6 and bought my mom a new I-phone 6+. we each got a new case and I got a lightining charger. my total out of pocket was $94.

how is straight talk cheaper? what am I missing?
