Ordered some more urbanist books - "Triumph of the City", "Wrestling with Moses" and "Urban Planning for Dummies." ;)
Decided to try out Amazon Locker and found one on my evening walk home. Had it delivered to "Gantin" on 666 Greenwich Street.
I must say it was a painless, idiot-proof experience.
Maybe in a future version, Amazon can make its smartphone app smarter and you just need to bump your phone to claim your stuff ;)
