Best Buy via eBay offers the Insignia Wave 2 Portable Bluetooth Speaker in Black, Blue or Red for $9.99 with free shipping. That's $30 off and tied with last month's mention, and among the least expensive portable Bluetooth speakers we've seen. It has a 2,000 mAh battery, built-in microphone, and up to 12 hours of battery life.
Some chains have retired their senior discounts. But these grocers still have deals for the silver-haired set.
