I searched everywhere and I finally decided to sell my iPhone 6s Plus to Igotoffer as they promised more than other secondhand buyers. Their payout was really good They sent me a label, I didn't have to pay to send them my phone. It arrived at their location in two days and a few hours later the amount promised was in my ChaseQuick account. Incredibly speedy service especially three days before X-mas.
If you need money to help with X-mas gifts or presents...
