I agree with their assessment that the A2Z Guarantee is a financial risk as the potential for counterfeits increases with scale. Amazon returns are shockingly easy and I am always given the benefit of the doubt. Makes sense that they would call that out as a risk factor.

That listing for the "yeezys" you linked, though, is a great example of something I would never even consider... I don't have a specific heuristic for how I select products, but this listing violates a lot:

-Prime availability

-Multiple sellers with extensive trading history

-At least 10 ratings and preferably at least 100

-Rating above 4* and maybe 3.5* if there are limited options

-Description that is written in legible English and reflects the copy on the item as found in a store

-And only after multiple searches using different search terms to identify the "right" keywords that bring the most relevant products

This has and will be a problem on any platform, whether it's eBay or Alibaba or on Canal Street in NYC [1]. If it seems shady, it probably is.
