Great design solution for shipping. Lately, I am having to send stuff to my mom's work, though she is semi-retired. She recently told me that the company is not happy with being the mailroom, understandable (though her office has her own personal equipment).
This is fantastic solution. Amazon has a list of lockers that you can mail your parcel/products/gifts too. I can almost see creating a surprise with a scavenger element with a bunch of $3.00 gifts. Maybe if this project is successful, they can help reorganize the post offices.
Thanks to Loida Valentin for the reference.
