Simply say “yes” to buy it. Products purchased using Alexa qualify for free returns. – Advertisement – Alexa previously was limited to reordering items someone had already purchased or recommending company-selected printers or laptops through a service called Amazon’s Choice. All the items now available for purchase must be eligible for Prime, Amazon’s membership service that includes unlimited two-day shipping. New items are being added daily to the list.Items ineligible for purchase through Alexa include apparel, shoes, jewelry, watches, Amazon Fresh, Amazon Prime Pantry, Amazon Prime Now and add-on items.While the Echo has turned into an unexpected hit for the connected home, Amazon will have to work harder to stay ahead of coming competition. Google plans to release its Google Home smart speaker later this year and Apple is rumored to be working on a competing device, too.
