>I complained and got some money back, except they credited the amount twice. When I contacted them about the double-credit, their system was down so they told me to contact them again later. Then later, they just told me to keep the money :/ I sell on Walmart Marketplace. Overall, it's the clear #2 third-party marketplace after Amazon. While nothing compares to Amazon FBA in terms of sales velocity, for FBM Walmart in some categories can be better than Amazon. That said, the Walmart Marketplace software platform is not great. A year ago, there was a good six months where the inventory system just did not work, causing many SKUs to incorrectly appear out of stock. I still strongly suspect that this happens often, just not so broadly.
