Consumers have a need for delivery speed, and Amazon.com Inc.’s one-day shipping satisfied it over the holiday shopping season.

Amazon headed to a $1 trillion valuation after reporting earnings of $6.47 per share late Thursday, blowing past the $4.04 FactSet consensus, and reaching record quarterly sales of $87.4 billion.

Moreover, the e-commerce and technology giant was able to pinch a few pennies, with the cost for cutting free Prime shipping down to one day from two came in less than the anticipated $1.5 billion.
