But saying something is sold by a specific party which I then choose to do business with, then substituting goods that are likely to be from any of numerous other parties, some of which I may be explicitly trying to avoid doing business with...I would at least be interested in hearing why that doesn't count as fraud or false advertising or some such, or maybe some trademarks issue.
At least, I'd love to hear a less rage-inducing justification for putting up with allowing this behavior than "it was buried in a ToS somewhere that lying about who my goods came from is okay, actually."
