Whenever I see an online auction where not all the cards are displayed, I assume there is something wrong. They're not hiding a bunch of PSA 7's and 8's under the PSA 4's. I assume all "hidden" cards are not on the top for a reason, and will almost ignore the value of those items when deciding what to bid on a lot.

In answer to your question, you as a potential bidder or consumer have every right to ask a question on the lot. They've taken the time to send you a couple of responses, but not taken the time to inspect the lot for you. My take is there is no gold in the hidden stuff, and they know it. Therefore there is no reason why they would point the obvious out to you. I'd move on.
