When Amazon launched the Fire Phone, it wasn't a top-of-the-line device. It did, however, come with a $650 price tag. When the handset immediately proceeded to not sell, Amazon started slashing the price. We've spent the time since watching the number drop.Now the Fire Phone appears to be getting cheaper by the day. Just this weekend we saw the device hit eBay at only $140. Now the phone's Amazon price has fallen to 0.Note, this is the 32GB model. The 64GB one appears to be gone. But hey, you still get a year of Amazon Prime. That means you're only really spending maybe $30 on the hardware. We're not too far now from the point when Amazon is essentially giving these things away.Source: Amazon
