I've never sold anything through amazon but find it interesting. I was looking at products and found that the number 1# product for a certain keyword was a generic alibaba product, and there was only the one seller for this listing. I looked on alibaba and found the exact product (exact same manufacturer code). The product goes for about 1.99$ on alibaba, but is being sold for 9.99$ on amazon. Now, when I looked at who the seller was on amazon, I noticed that is was also the exact same seller/manufacturer on alibaba. So this manufacturer is selling his product for 1.99$ on alibaba and then also selling it for 9.99$ on amazon. What are your thoughts on buying from him on alibaba, then directly competing against him by hijacking his listing by slightly undercutting his cost? Also, is there any way he could connect the dots that I'm the same guy who purchased it from him on alibaba?
