I can buy Sam's Club brands and/or sizes first party through Walmart.com, and I could do so before the Jet.com-ification of the Walmart website... it just wasn't well known until recently.
I know... that's part of what makes it so interesting.
There are still 3rd party sellers somehow selling Walmarts own product cheaper via Sam's Club. Or sometimes for products that aren't available on both public facing sites. (Sam's and Walmart)
Which is probably why Walmart made the effort to better integrate the brands.
