President Trump in recent days has railed against Amazon.com, claiming it is perpetrating “a scam” and its deliveries cost the Postal Service “a fortune.” But with a law he signed late last year, Trump gave Amazon and other online retailers a huge opportunity to expand how much business they can do with the federal government.

Under the law, federal agencies would soon be able to spend significantly more money on all sorts of commercially available products from an approved list of online retailers — without having to go through cumbersome procurement regulations.
