Eh, a big part of GameStop’s recent strategy has been getting into collectibles trading. eBay is one of, if not the, biggest market for collectibles, and they own TCGPlayer. That said, counterfeits and other fraud is a problem on eBay. One of the proposals is to use GameStop stores as authentication hubs, so listings can be verified.

Additionally, eBay spends a lot, arguably way too much, on marketing, not to mention bloated upper level compensation packages. Then there’s the friction of the service itself, like seller caps (ostensibly to combat fraud, but a bit overzealous).

I think there’s far too much potential for improvement to call the claim “delusional”.
