ILuckyDog via eBay offers the Wireless Qi Power Charging Pad in Black or White for $6.28 with free shipping. That's tied with our mention from last week as the lowest total price we've seen. (It's also a current price low by $4.) It's compatible with select HTC, Lumia, Nexus, Galaxy, and Note models.
Note: Expect this item to take four to eight weeks for delivery.
