The first Amazon.com Inc. building on Long Island is expected to be up and running later this year.

A company representative told Patch that Amazon recently signed a lease in Bethpage. The building will be used to support Amazon's customer fulfillment network, the representative said.

Fulfillment by Amazon allows customers to store their products in Amazon's fulfillment centers, and Amazon will in turn pick, pack, ship, and provide customer service for these products. Watch a video on Fulfillment by Amazon to learn more about the service here.
