Shcifang via eBay continues to offer the U8 Bluetooth Smartwatch for Android and iPhone in six colors for $9.29 with free shipping. That's tied with our mention from a week ago as the lowest total price we've seen. (Outside of other eBay sellers, it's the best price now by $2.) Features include a passometer, calendar, call sync, calculator, clock, and stopwatch. Note that not all features are compatible with iPhones.
Note: This item ships in bulk packaging and does not come in a retail box. Expect three to eight weeks for delivery.
