Quick Ship Electronics via eBay offers the open-box Fugoo Tough Rugged Bluetooth Waterproof Speaker in Black for $35 with free shipping. That's $45 under the lowest price we could find for a factory-sealed model. (For further reference, we saw an open-box model bundled with a mount pack for $45 in last month's mention.) This waterproof speaker features two 28mm neodymium tweeters, two 39mm neodymium aluminum mid/woofers, two 43mm x 54mm passive radiators, and a frequency response of 60Hz to 20KHz.
Note: A 1-year Quick Ship Electronics warranty applies.
With these companies, it might be easier than you think to negotiate your monthly bill down.
