Target and Walmart take online returns at their stores, which no one in the supply chain likes. They will take bad suppliers to the woodshed if too many returns of an item. Hence they have skin in the game to carry quality products
I didn't say I trust reviews on Target. Paid reviews exist everywhere. But if I have to choose, I'd trust Target's first. Amazon's extensive 3rd party marketplace is set up in a way that encourages vendors to game their system. Amazon does nothing about it because it's good for business.
And I trust Target's products are genuine and what you receive is what's in the product description, because they sell them in stores.
