Cashforiphones.com gave me an online quote of $203 for two iPhone 4S phones I very accurately described for them. They sent a box and I mailed the two phones to them as directed. A week later I received an email saying their technicians decided they would pay $21 total for the two phones and a check was in the mail. I called and asked them to cancel the check and return my phones because I had higher local offers. They would not.
I believe they are running a scam by offering high quotes and sending a much lower check before anyone can stop them. I highly recommend no one use this cash for electronic website.
