Right now, Best Buy via eBay is selling the HTC One M8 for just $299.99. That's the off-contract pricing too. They currently have the Sprint, Verizon and AT&T models available as well. So you can choose the one for your carrier. Unfortunately, T-Mobile doesn't allow third-parties – like Best Buy – to sell phones for them anymore. The HTC One M8 features a 5-inch 1080p display, Qualcomm Snapdragon 801 chipset, 2GB of RAM, 32GB of storage and a microSD card slot. It's still a pretty capable smartphone, not to mention a great looking one.
