Whole Foods Market Inc. (WFM) shareholders congregated at the company's Austin, TX headquarters and voted to approve the company's purchase by Amazon.com Inc. (AMZN) - Get Amazon.com, Inc. Report Wednesday. 

The two companies are expected to close the $13.7 billion deal in the second half of 2017, pending regulatory approval and other closing procedures. 

Amazon shook up the grocery world when it announced the purchase of Whole Foods earlier this year. The deal was announced just days before food delivery service Blue Apron Holdings Inc. (APRN) - Get Blue Apron Holdings, Inc. Class A Report debuted on the stock exchange, and Blue Apron's stock has not been able to recover since.
