So now I got that Sprint $50 unlimited everything plan. Used $60 in reward certs and a $30 gift card. Sold my Galaxy S5 the next day for $350. so that's $440 paid on an $850 phone. I still got an iPhone 5 I might trade into Sprint for $200 if I can't find a buyer. That will leave me with a final out of pocket cost of $210. Probably use the reward points on all my credit cards which adds up to $150 across 3 cards to help pay for some of that.
