Last year, Google acquired Waterloo-based startup BufferBox, which provides shipping locker service to make it easy to get things delivered reliably even when you’re not sure where you’ll be when they’re arriving. The startup built its service on the idea that people never want to see another missed delivery door tag ever again, and began rolling out availability in Toronto, a big consumer market near its HQ last year. BufferBox is now venturing further afield (as teased earlier this year), with a program expansion in San Francisco that takes its kiosk service closer to Google’s home territory. The BufferBox model allows local businesses to essentially become a substitute post office, receiving packages on behalf of BufferBox users during business hours when they’re guaranteed to have someone on staff to accept delivery.
