Walmart offers the Huawei Union No-Contract Android Smartphone for Virgin Mobile, model no. HUAY538, for $29.82. Opt for in-store pickup to dodge the $4.97 shipping fee. That's slightly under last month's mention with another carrier and the lowest price we've seen. (It's the best now by $10.) It features a Qualcomm 1.1GHz processor, 5-megapixel rear-facing camera, 8GB internal memory, 1GB RAM, and Android 5.1 (Lollipop) OS.

Update: The price has dropped to $28.37.
