Hi Kolev,<p>It depends on what type of online retailer you are. We developed esell.io for people who are occasionally selling something they create on their own websites, blogs or social media sites.<p>Considering these small online retailers it really is "only 5%" compared to the fees of eBay or Amazon or most of the marketplaces. It's "only 5%" if you compare it to the cost of developing and opening your own e-commerce website. Or even if you compare it to a monthly subscription fee of some other e-commerce platforms.<p>And you're right - this will not work for high-volume low-margin online retailers.
