Unless an item is gold or silver the price probably is not going to change year to year. When I am at the convention as a seller, I am strictly looking to unload my excess inventory. Last year I took many items and just repriced them lower to try to sell them but then I am not in the chip business and looking to make a profit. As far as not having items priced I agree that it is pretty much a pain as a buyer to have to ask the dealer what every item is priced at.
