Amazon is now price matching Best Buy’s Deals of the Day offer on the Beats by Dre Powerbeats3 In-Ear Wireless Headphones. Over at Amazon the Black, Siren Red, White and Flash Blue colorways are all down at $109.99 shipped, to match Best Buy’s offer on the red set. While Best Buy’s offer is available for today only, it’s hard to say if these will jump back up tomorrow at Amazon as well. This is matching our previous mention, $80 below Apple and the best we can find. Rated 4+ stars from over 12,000 Best Buy customers. More details below. more…
