Walmart Marketplace on the website runs on a similar business model to the Amazon marketplace, so there are third party sellers on their website. In some cases Walmart sells goods on consignment, so it does not own the goods in question, but it is still the seller of record. So, there is a good chance that if you buy something in person at a Walmart that the products you are buying were consigned from the brand, but you would never know. Products stocked at Walmart itself go through a very rigorous vetting process, so in general you will never find anything on Walmart shelves that is truly 100% crap. As far as I know, there is no commingling with Walmart. All online reviews are fake; there are just some products and places where the reviews are less fake than in other places. In general people don't do as much Walmart review fakery because their website gets so much less traffic and sales than Amazon does. The fakes go where the money is. Unlike getting a product on store shelves which requires passing through a rigorous, sometimes corrupt, but difficult-to-fake process, getting a product on Amazon or Walmart Marketplace is as easy as uploading a spreadsheet or filling out a product description.
