Take the deal. How much more do you think you will get on the open market. You can get new phones with cell companies for next to nothing. That is $46 per phone more than any person with half brain would pay.
other places - http://www.buymytronics.com/ -try http://www.gazelle.com/ -
or for only phones try http://sellmyoldcellphone.com/
they both give amazon gift cards or paypal payments directly and THEY pay for the shipping and send u the box I believe
