Best Buy offers the Jam Touch Wireless Portable Bluetooth Speaker
in four colors (Black pictured), model no. HX-P550, for $19.99
. Opt for in-store pickup
to dodge the $3.99 shipping charge. (Amazon
charges the same in three colors with free shipping for Prime members.) That's the lowest price we could find by $12. It features a 30-foot range, five hours of continuous playback, and 3.5mm jack.
