Wireless headsets are a godsend for busy parents who already have too few hands. Amazon’s having a one-day deal: a decent selection of Bluetooth headsets are on sale for $20. I see a few Motorola and Samsung units, plus a bunch of others. The Motorola HS850 pictured here is usually $99.99. Get yours quick — hopefully they won’t run out (last time I reported a sale on Motorola headsets they did).
