Macy's offers the Google Chromecast Audio Media Player for $15. Pad your order over $25 or with a beauty item (they start at $3) to bag free shipping; otherwise, shipping adds $10.95. (B&H Photo Video, Best Buy, and Google via eBay are matching this price with free shipping.) That's the best deal we could find by $5 and the second-lowest price we've seen for this player. (We saw it for $2 less three days ago.) It features dual-band 802.11ac wireless and compatibility with Android and iOS devices.
