Why it's revolutionary: "No one disrupts retail like Amazon," Natalie Berg, retail insights director at Planet Retail RNG, told Business Insider. Amazon is ramping up its presence in fashion and groceries.
In June, Amazon launched Prime Wardrobe, a try-before-you-buy service, where customers are sent clothing that they are able to try on before deciding what they want to keep. The more items they keep, the bigger the discounts they receive.
Amazon also announced plans to buy grocery chain Whole Foods for $13.7 billion in June. The chain has 465 physical stores, which will allow Amazon to expand its footprint and have a presence in key cities across the US. Physical locations are key for Amazon, as it seeks to offer more Prime services across the US, such as same-day delivery.
