Amazon.com Inc. had a headline-grabbing second quarter, both in the news and on its books.

North America’s largest online retailer generated North American net sales of $22.37 billion in the period ended June 30, up 26.6% from $17.67 billion. International sales were up 16.7% and the Amazon Web Services unit grew 41.9%. Sales by marketplace merchants accounted for 51% of unit sales globally, up from 49% a year ago.

Amazon announced plans to buy supermarket chain Whole Foods Market Inc. during the quarter in a deal valued at $13.7 billion. That news sent other supermarket stocks tumbling, at least temporarily. Whole Foods, which reported its Q3 earnings Wednesday, said it had generated $300 million in net income on $12.38 billion in sales for the 40 weeks ended July 2. It provided no commentary on its pending acquisition by Amazon. On the Amazon earnings call Amazon chief financial officer Brian Olsavsky said Amazon is excited about the acquisition, noting “we think they are very customer-centric just like us. We are really glad to join up with them.”

Amazon reported net income of $197 million, down from $857 million a year earlier.

Apart from the Whole Foods surprise, elsewhere during the second quarter Amazon announced nine new U.S. fulfillment centers—three in New Jersey, and one each in Georgia, Connecticut, Colorado, Florida, California and Oregon. It also announced it would make customer loyalty program Prime available to consumers on government assistance programs for $5.99 a month for one year, as opposed to $10.99 monthly for consumers not in an assistance program. Prime is the membership program that provides unlimited expedited shipping to members among other perks such as streaming video and music.

Amazon does not say how many Prime members it has, however estimates from Consumer Intelligence Research Partners put the U.S. member count in June at 85 million, equal to 67% of U.S. households.
