Is Cashiphone a reliable site to sell my IPhone 5S on?

I recently sold my IPhone 5S that has part of the upper screen cracked but it still works and turns on and they said they will pay me $30.00 cash and send it into my PayPal Account within 3 business days and it's been 5 days now. Has anyone else used Cashiphone to get cash for their IPhone and is it a reliable website to sell on?

I don't know, but that's a terrible price, even if the screen's cracked

Weekends don't count. Neither do national holidays.
