Amazon Lockers are self-service kiosks placed in shopping centres, retail stores, transit stations, and other access points in areas with high package density. Customers select an Amazon Locker as their shipping address, receive a pickup code when the package is delivered, and collect their package at their convenience. The Amazon Locker addresses concerns of parcels being stolen or customers missing the mail delivery as well as creating convenience for customers who are unable to take delivery of an item at home or at work. Amazon Locker launched in September 2011 in New York, Seattle, and London and continues to expand its network nationally throughout the US and UK. Amazon recently did a publicity stunt in San Francisco where they planted a shipping container sized locker containing a Nissan car. The car giant then posted a competition to win the car if they are able to work out the code that would unlock the container.
