Smart containers can sense you're running low on inventory and keep you stocked up, automatically ordering refills from Amazon. A South Florida start-up company called WePlenish created a container that does just that, and it has Amazon's blessing. 

Launching today on Kickstarter is the WePlenish Java: a plastic bin that sits on your kitchen countertop, shopping Amazon on your behalf, provided you're an Amazon Prime subscriber. The company is offering a special price of $20 for early Kickstarter backers, but when the container arrives to Amazon in October, it'll be priced at $40 (roughly £30 or AU$55).
