They just had a July 4th deal on here for S3 accessories. Got an OEM battery with the NFC chip and S3 specific battery charger for $38. Also picked upan S3 usb dock connector for my iMac for another $38. Free 2 day shipping as well and no tax. Saved $25 overall. Good deal thanks to this board.
When it comes to this phone, I just don't trust the cheap Chinese knock-offs from ebay/Amazon. Plus, I use my NFC tags daily, so I needed OEM. I'm not saying the cheap batteries from ebay don't work, I just don't trust them with a phone i paid $550 for (unlocked US version)
