A mere three days after Motorola started selling the Moto G unlocked online, giant retailer Amazon is bringing the budget-friendly smartphone to its shelves. Pre-orders are being accepted as we speak, with the 4.5-inch device being priced at $179 and $199 for the 8GB and 16GB models, respectively. Unlike with Motorolas promise to ship the Moto G as early as December 2nd, Amazon has the arrival date listed for a couple days later, on December 4th.
