One small thing I'd like to see improved is increasing the search radius by zip code. I have to punch in multiple zip codes if I want to search the redboxes throughout my city. If you implemented a 'search 10-20-30-etc' mile radius it would be extremely helpful.
This would be so helpful. I live in the suburbs of San Antonio, and could drive to 5-6 different zips in 10 minutes or less. Not counting the multiple zip codes in SA I drive through daily.
