Amazon Prime Day 2019 is here. Starting today and for the next 48 hours, bargain shoppers can cash in on some of the best discounts on electronics and other gadgets. Some of the main items that are hugely discounted are 4K TVs, Echo speakers, smart home supplies, tablets and DNA tests. Experts encourage shoppers to buy early to secure the best items while they’re still in stock. Prime Day is exclusive to Prime subscribers, but people can sign up for a trial to take advantage of the deals. There will also be deals at Whole Foods, which was bought by the online retail giant back in 2017.
