Brad's Deals Editor Michael,
This Philips Wireless Bluetooth Speaker drops from $149.99 to $39.99 at Woot. Shipping is free with an Amazon Prime account or when you sign up for a Prime free trial. Otherwise, it adds $6. However, this is still the best price we found for one by $3 even after adding the shipping charge. These speakers have NFC and feature built-in mics for hands-free phone calls. Sales tax is charged in most states.
