You only really reap the benefits of Qi wireless charging if you scatter the pads all around your home and office for quick charging sessions throughout the day. Luckily, at $10 each, you can now afford to do just that. [Qi Wireless Charging Pad, $10 with code F53C8RAU]
Update: It looks like this code can only be used once per account. If you really want to stock up, you could create new Amazon accounts and sign up for free Prime trials, though that might not be worth the trouble. Sorry!
