This Portable Wireless Bluetooth Speaker drops from $ 19.99 to $ 10.99 to $ 8.99 with code 4SWBS at Mini In The Box through 4/3. This ties with the lowest price I’ve seen to date and is a current price low by $ 5! It features a waterproof design, suction-cup for easy mounting and includes a USB charging cable. Note that you must uncheck "shipping insurance" at checkout, otherwise a $ 0.99 fee is added. There is a limit of one speaker per account. Shipping times are currently 10-20 days, but they have 400 speakers available in their U.S. warehouse so shipping times are reduced to 3-7 days . There is no sales tax.
