I am just curious what everyone thinks to be the absolute minimum value for an iPhone 6, 64 GB silver with apple care plus good through 9/18/16. It is in brand new condition visually. Brand new accessories from my iPhone 6s box. I am selling on CL. Got a couple emails so far. But they all want to know my "lowest price." I don't want to rip myself off. Just looking for opinions... Thanks in advance!
