As one of its daily deals, A4C offers the used Samsung Qi Wireless Charging Pad in Black for $6.99 with free shipping. That's a buck under our January mention and the lowest we've seen for this charging pad. (It's also $2 under the best price we could find for a new one.) It charges compatible Galaxy smartphones and other Qi-compatible devices. Deal ends today.

Note: A 30-day A4C warranty applies.
