NEW YORK ( TheStreet) -- Amazon.com ( AMZN) is trying to make it easier for you to receive your orders. This time, the online retailer enlisted the help of a competitor. Amazon has been installing what it calls "lockers" in a number of nationwide retail chains, including 7-Eleven, Rite-Aid ( RAD) and Walgreen ( WAG,) stores. Some of those retailers are open 24/7. The idea is for customers to have their Amazon packages shipped to a nearby "locker" -- or one-time use private mailbox -- so that customers don't have to stay home to receive their orders. If you choose to have your package delivered to a nearby retailer, Amazon ships the package there and sends you an email with a special code that unlocks the locker. That unlock code is good for three days. Amazon is now expanding the program. According to Reuters, the world's largest online retailer is adding Staples ( SPLS) to their list of delivery "locker" partners. Staples (as does all of the Amazon locker partners) gets a small fee for housing these delivery bins in their stores. But, in some ways, the deal could turn out to be awkward and somewhat counter-productive. Some of those deliveries will be for the same office supplies for sale on Staples' own store shelves -- purchased instead, online, from Amazon. Staples hasn't announced further details. --Written by Gary Krakow in New York. >To submit a news tip, send an email to: email@example.com.
