Earlier quoted context omitted.
I buy a lot from Walmart now, to drive business away from Amazon (I would never have typed these words a few years ago...). First thing I do is click Retailer = Walmart.com.
Remember that Walmart and Best Buy also sell a lot of 3rd-party stuff now. I find it strange that on their site I always have to filter by Retailer=Walmart.com to get their listings and even then, it sometimes filters out some of their own listings.
Every time you hear, " sold on Walmart website!" it's always a reseller, not directly from them.
