We tend to focus so much on online advertising that it is easy to forget there are other ways to make money online. Like good old-fashioned sales. Online sales in the third quarter across all categories (excluding travel) rise 23 percent to $28.4 billion, according to comScore. (Including travel, e-commerce sales are up 18 percent to $48.6 billion). Total e-commerce sales for the year are on track to hit $200 billion. No wonder Amazon’s stock is hitting new highs.
