Have you been wondering if Google really ran out of the Galaxy S4 GPE? Well, maybe there were a few left over. That would explain the cache of devices that just popped up on eBay. Someone has acquired a number of the devices and is selling them at a steep discount. Just $499.99 for an unlocked Google Play Edition smartphone. That's $150 off what Google was selling it for a few weeks ago.
The Galaxy S4 is still a capable phone with a Snapdragon 600, 2GB of RAM, and a 5-inch 1080p Super AMOLED. This is the exact same device you would get from Google, if it was still selling them. It supports AT&T and T-Mobile's networks, so just drop a SIM in and go.
The deal includes free standard shipping in the US, along with international shipping for a significant upcharge. $500 is still a lot for last year's phone, but there was no GS5 GPE announced at I/O. Maybe you can wait it out, or maybe you just take the deal. Your call.
