Amazon dominates in the online retail space. Can the competition compete and steal market share?

I agree with you that costco is more user-friendly even though they don't have as much variety. But lately I only order through them and it's very convenient that they have a rather responsive support service that I contacted at https://costco.pissedconsumer.com/customer-service.html where they could help me when I had a problem with one order. As a result, I contacted customer support several times and both times they quickly helped me solve my problem with the order.

I believe that new big players have less chance of competing with Amazon now, but small niche marketplaces perform pretty well.

Even if all of the above have better customer service(even though Walmart imo is not) - they lack one huge thing: E-presence as much as Amazon does and delivery system. Amazon cuts so much on delivery prices on top of having pretty low prices itself - no amount of customer service going to fix having higher prices for 95% of customers. Add on top of that that it constantly has improving listings(I know a lot of new companies like Weby Corp http://webycorp.com/ who focus heavily on improving listings) that you can 360 degree items and read thousands of reviews - and you get yourself a trustworthy and budget friendly option, that delivers within days after you order on top of being reputable and scamer free. Simple as that
