I was in a book store in the 1990s (I won’t name which one because it’s still in business; it’s not one I’ve worked at though) and they had a bunch of comics in the front of the store. There wasn’t any prices on the comics or on any sign nearby so I grabbed some and took them to the front to find out the price. It turned out to be a percentage of the price original price or something like that. I decided that only one was at a price I wanted to pay, a Howard the Duck comic. The guy actually made an “Oooo, big spender!” remark . While I have shopped there from time to time I think that’s probably the big reason I don’t shop there too often. It also illustrates one of the reasons I don’t like to ask what stuff with no marked prices cost; things can be awkward if the buyer learns the price and decides it’s too expensive. I’m sure I’ve passed on a few decent deals simply because the seller wasn’t up front with the price.
