Best Buy offers the Huawei Union No-Contract Android Smartphone for Boost Mobile for $9.99. Opt for in-store pickup to avoid the $5.49 shipping charge. That's $20 under our mention from three weeks ago and the lowest price we've seen. (It's a current low by $15.) It features a Qualcomm 1.1GHz processor, 5-megapixel rear-facing camera, 8GB internal memory, 1GB RAM, and Android 5.1 (Lollipop) OS.
