When the lights go out and the doors come down at your local Costco warehouse, don't worry—Costco.com has you covered. The website has an expanded selection of items, a variety of services and a number of features to make shopping easy and fun.

Making the Costco.com experience as seamless and efficient as possible is Costco's increasing agility in shipping items, from small to big and bulky—you know, goods that won't fit in the family car, like a gazebo.

And whether your needs for a product are planned or last-minute, Mike Parrott, Costco senior vice president of U.S. e-commerce, wants members to know that they can get everything they need—including appliances, electronics, furniture and much more—fast.

"The idea is that we continue to speed up delivery," Parrott says.
