> Unfortunately, no physical retailers around me have random things like 3D printer filament, various specific fasteners, or a particular inexpensive picture frame. Amazon wins at sheer variety of inventory. They don't have to have a physical store near you. > Also, if a particular popular brand/model is at a big box store, the Amazon listing is almost certainly the actual thing. Random off-brands might be fake, but you run the same risk at Walmart as you do with Amazon then. I highly doubt it. Amazon doesn't vet its sellers to well, and co-mingles supplies unless you pay a fee. I think Walmart probably does it better because it isn't trying to court every seller under the sun.
