Microsoft Store offers the Scosche boomCAN Portable Speaker in Black for $9.97 with free shipping. That's tied with last week's mention as the lowest total price we've seen. (It's a current price low for any color by $4.) It features 35mm drivers and a rechargeable Lithium-ion battery, and includes a USB charging cable and a travel pouch.
It's so easy to save big at Ulta that you should never pay full price -- whether you're buying makeup, fragrance or other products.
