From looking at these videos it seems things haven't changed much. Why do so many of the dealers insist on putting items in their cases that aren't priced?

As a potential customer, I would like to be able to look at the item and see a price prominently posted on the front. I know the price may just be a starting point, but I really don't want to have to ask the dealer what the price is for every item I'm potentially interested in. It wastes his time and mine and can often lead to the dealer getting frustrated with you, when all you wanted to know was his asking price.
