Walmart offers the Huawei Union No-Contract Android Smartphone for Virgin Mobile, model no. HUAY538, for $24.92. Opt for in-store pickup to dodge the $4.97 shipping fee. That's $2 under our mention from two days ago and the lowest price we've seen. (It's the best now 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.
