The market price is not their concern, they are meant to hand the cards out, not sell them. If I give you $5 and ask you to give it to a friend, keeping it for yourself for any reason – "it's only $5," "actually, times are tough", etc. – is not justifiable, it is theft. If you cannot be trusted with $5 or you cannot even be trusted with a cardboard trading card, provide whatever rationale you like, it means you are of poor character.
This new bit that business that store owners are businesses and have to do what businesses do actively conflicts with the sob stories of previous threads where LGSes are small businesses run by people who love the hobby – just like you or me! – and so we must support them.
Another concerning matter in the replies here is that the argument being presented isn't "this is just a few bad apples, most LGSes will distro it properly" – as was the previous argument when I shared my experiences seeing LGSes engaging in shoddy practices. Again, I had no doubt about this in the past, but anyone on the fence might wish to take note of this.
LGSes play a key part in making this hobby worse by actively playing a key part in scalping. If you believe otherwise, you are kidding yourself. Going forward, I'm going to assume anyone who argues otherwise is an LGS owner themselves, arguing only in their best interests, and against the best interests of most everyone else.
