MiniInTheBox offers the Xiaomi 802.11ac Dual-Band Wireless Router 3 for $25.99 with free shipping. That's the lowest price we could find by $12, although it was a buck less in December. It features 2.4GHz and 5GHz simultaneous networks, 128MB RAM, and the XiaoMi MiWiFi app.

Note: Uncheck the "shipping insurance" box at checkout to remove the 99-cent fee.
