I don't see a problem with the scenario. I have dealt with a few buyers who have sought volume discounts specifically because they were planning to resell and needed a profit margin. I have also encountered a few collectors (who are really dealers) who tried to low-ball me when I first started posting and only offered face value, no matter how valuable the chip. But if we're able to set a price I can live with, I welcome all types of buyers.

If you are new to the hobby and don't know the real value of chips, though, "seller beware" is just as appropriate a warning as "buyer beware."
