Amazon.com has reported second quarter sales are up 20% to $63.4bn (£51bn), but added profits were lower than expected as it invests in speeding up delivery times.
Posting results for the second quarter, ending 30th June 2019, Amazon reported profit of $2.6bn and said its income would slump in the current quarter.
Net sales increased 20% to $63.4bn (£51bn) in the second quarter, compared with $52.9bn in second quarter 2018, as investment in faster shipping starts to pay off, said Amazon.
In books, Amazon did not break out details other than highlighting the introduction of the new Kindle Oasis.
"Customers are responding to Prime’s move to one-day delivery — we’ve received a lot of positive feedback and seen accelerating sales growth,” said Jeff Bezos, Amazon founder and c.e.o. “Free one-day delivery is now available to Prime members on more than ten million items, and we’re just getting started.”
