>Buyer beware - my wife hates Amazon and goes out of her way to not purchase from them. She has encountered several vendors on Walmart marketplace that simply place orders with Amazon at 100% markup - the packages arrive in Amazon boxes w/ a receipt showing the actual cost paid at Amazon. Total rip-off.
I sell on both Walmart and Amazon. As somethingwitty1 said, this works in multiple directions; people dropshipping ittems from Amazon directly to Walmart customers, from Walmart to Amazon customers, and from both to eBay customers.
It's also forbidden. Both Walmart and Amazon explicitly warn against shipping items to customers in competitors' boxes; Walmart even explicitly bans tracking numbers starting with "TBA". If your wife reports that this is happening to Walmart buyer support, the sellers won't be there for long; recent anecdotes say that both companies are really cracking down on dropshipping.
>When ordering electronics from Walmart Marketplace, particularly TVs, I’ve found that the marketplace sellers freely substitute makes and models.
Ugh. All I can say that I've also had less-than-positive experiences when buying from other sellers on both platforms. Amazon is notorious for allowing anyone to open a seller account. Walmart is in theory supposed to be much stricter in examining applicants' qualifications, with many waiting for weeks or months. While this is great from my perspective (both in terms of improving the overall quality of third-party sellers, and minimizing my competition), the incompetent and crooked are still getting through; Walmart recently allowing non US-domiciled sellers (i.e., Chinese) doesn't help.
>I’ve not had any issues with the items sold by Wal-mart actual, those you can buy with confidence.
Agreed. Amazon commingles its own inventory and that of third-party sellers that Amazon handles storage and shipping for (FBA); as a result, my own confidence in the genuineness of, say, household staples from Amazon has plummeted. I think Walmart does not do so with WFS, its FBA equivalent. In any case WFS much less used than FBA, because there is little advantage for sellers to do so over fulfilling items themselves.
