I have found in era evidence supporting sarsnick's claims to how merchant-diving should work (I think his link showed a created date of 2003). Not sure if possible with Titanium client, but here you are...

Merchant-Diving Explanation (5/10/01):

I've pulled 40 silks out of them before, and that was before I knew about the merchant-diving technique to get stuff that was off the bottom of the inventory list.

Do you mean buying the junk at the end of the list to get more things to pop higher or some other trick?

Sort of.

You will need one (1) of the items that you're looking for.

What you do is find something in the visible inventory that you can easily
deplete, either because it's cheap, or because you think there aren't that
many in stock, and buy them all. This leaves an open spot in the merchant's
inventory.

Then sell the thing that you're looking for (spider silk, HQ bear pelt,
rune of rupturing, whatever).

If the merchant has none in stock, it will appear in the open slot. Buy it
back and move on to the next merchant.

But if the merchant has some in stock, the open spot will remain empty,
because the thing you sold was placed with the existing inventory off the
bottom of the list.

Then you have to start depleting the merchant's inventory until the stuff
you're looking for pops up from the bottom.

Ahhh, that's a nice improvement on the way I'd been doing it - I
didn't know the "sell one and watch the slot" trick. I've been just
crossing my fingers and buying all the junk from a likely merchant,
and hoping for the best.
