Walmart offers the Google Chromecast Streaming Audio Media Player for $30. (Best Buy has it for the same via pickup.) Opt for in-store pickup to avoid the $5.97 shipping charge. That's tied with our mention from a week ago and the lowest price we could find now by $4. It features dual-band 802.11ac wireless and compatibility with Android and iOS devices. The set includes one 3.5mm audio cable.
