Amazon Storefronts is a way for small and medium-sized businesses to sell products directly through Amazon. The Amazon Storefronts web page caters only to customers who want to buy from US-based SMBs, including local artisans, family-owned businesses, and innovators.
Amazon Stores offer merchants the option to have an online store dedicated to their Amazon listings only. They’re an improvement on Amazon Pages, with a lot more content, options, and flexibility. For example, merchants can now have dedicated pages for each of their product lines, use the advantage of HD Video and most importantly, differentiate their brand from their competition.
