The Echo Dot, Amazon's $50 in-home assistant, was briefly free on Amazon today, thanks to an "Audible" discount that got added at checkout. The discount applied to both black and white models, though it now appears people trying to score a free Echo Dot are being told the items are no longer in stock.

We've reached out to Amazon for clarification on the sudden super-sale. Whatever the reason, happy random Prime Day, folks.
