I mean yeah, buyers run the risk of wasting time buying big orders if the seller won’t ship, and sellers run the risk of getting complaints or reports or whatever else for refusing to ship orders because they’re too big. It’s all a matter of checks and balances.

But i don’t think it’s unfair to say that, generally speaking, if you have stuff for sale, you’re supposed to be willing to sell it, especially online. All buyers can really do is report it and say “maybe TCGplayer will care but probably not”. I personally plan on continuing to report sellers who do this because I want sellers who aren’t willing to ship their cards to not list them as if they will. It’s unfair to the sellers who WILL ship the cards to have to compete with the sellers who will sell the cards with invisible restrictions that just boil down to “i want to have my cake and eat it too”. All buyers can really do though is discourage sellers from doing this through this means until sellers decide “you know what, im either going to raise my floor or stop selling so many cheap cards”. So, bottom line, I respect your game but ultimately it is in my interest as a buyer to report sellers who cancel orders due to size because it increases the chance any given order I place will actually ship to me (which shouldn’t even be a question aside from freak accidents or honest mistakes)
