Instagram will now let you buy things directly through the app

After years of ogling beautiful images of food, fashion and design on Instagram, people will now be able to buy things they see and like directly through the app — providing instant gratification for the trend-obsessed and a new source of income for parent Facebook Inc.

Starting Tuesday, the photo-sharing app is testing a shopping feature, called Checkout, with a handful of retailers including Nike Inc. and designer fashion platform Revolve.

“Over time, as we are creating value for people, this could be a significant part of our business,” said Vishal Shah, Instagram’s head of product.
