I think the dealer serving a list is doing a big, big, BIG service for the hobby. In most cases he is getting $7 to $8 per chip. As I stated before, I know chippers that live in LV and subscribe to a service.
I seen a post from George Conrad, saying he had room on his list for a few and he keeps the list at 25. That is 25 chippers getting one of every chip.
I am not pushing George's service, as there are several others in LV, such as Cheques In The Mail, Gaming Times, ETC. It is a good way to insure you get every chip, including rack chips.
