On multiple occasions, I have gone directly to the supplier only to have the products show up in Amazon packaging and delivered by an Amazon driver. Off the top of my head, a robovac from Eufy and athletic shoes from a local shoe store chain. The shoes really fucking pissed me off because I actually went to the physical store so I could “support local”, but my feet are an “unusual” size, so I had very few options outside their online stock. And ordered through the in store system, but the shoes were still delivered by Amazon, except I didn’t get the easy return options that I would’ve had if I just ordered from Amazon to begin with.
