While we're partial to last-gen flagship deals, ones for current flagships may be just as good under certain conditions. The Samsung Galaxy S8+ is the next device to make the list, with it being offered at a bargain price of US$629.99 on eBay at the moment.
The S8+ doesn't need much in the way of lauding, so this is a deal that sells itself. It sports a 6.2-inch SUPER AMOLED QHD display, with an 18:5:9 aspect ratio that gives it the feel of something akin to a regular 5.7-inch phone, 4 GB of RAM, 64 GB of storage, 12 MP rear camera with OIS, 8 MP selfie shooter, iris scanner, rear fingerprint sensor, and a 3500 mAh battery.
This particular model is the dual-sim variant that's powered by Samsung's in-house Exynos 8895, and runs on Android 7.0 Nougat. It's also new, unlocked, and supports most international bands. It cannot be used on CDMA carriers like Verizon, Sprint, and Boost, though.
