Endless is one of Amazon's first entry into the boutique online retailer world. This particular offering focuses on handbags and shoes. This definitely isn't the Amazon you're used to. The navigation is extremely well done with neat AJAX filtering and sorting. What shoppers will be extremely happy about is the negative $5 overnight shipping. Return shipping is also covered by Endless so you can purchase shoes without risk.
It's clear that Amazon is following in the footsteps of Zappos. Whether they'll be able to catch up or surpass what Zappos has accomplished remains to be seen. What's clear is that Amazon is taking the shoe and handbag industry seriously, so having the two large retailers competing will only mean better service and better prices for us.
