Selling on Amazon could be a big mistake for SMEs. At first you'll enjoy great traffic from buyers, but once the item is popular, Amazon themselves will start "selling" them under their own brands at cutthroat prices. What ever happens, they win in the end.

If Lazada, shopee, those "Malls" or favourite sellers are still quite expensive than other sellers

So yeah, to me Amazon is ruthless, cutthroat and despicable. All it does is just getting profits non-stop. Its the modern "Standard Oil" of the late century.
