Sales were strong in several sections of Amazon's massive marketplace.

For the quarter that ended June 30, Amazon earned $158 million, or 37 cents per share. Amazon earned $78 million, or 19 cents per share, in the same quarter last year.

The company's revenue climbed 41% to $4.06 billion, including a 35% leap in North American sales.

Sales of things like books, CDs and DVDs rose 31% to $2.41 billion, while electronics and other general merchandise sales soared 58% to $1.53 billion.

One closely watched measure, the company's net shipping cost, climbed to $128 million from $75 million a year earlier.

But Amazon also noted that revenue from shipping — which includes earnings from its membership-based two-day shipping program, Amazon Prime, and its third-party shipping program, Fulfillment by Amazon — rose to $186 million from $152 million.

For the current third quarter, Amazon predicted sales of $4.20 billion to $4.43 billion; analysts had been looking for $4.23 billion in revenue.

The company increased its sales forecast for the rest of the year to a range of $19.35 billion to $20.10 billion. Analysts were expecting $19.60 billion.
