Of course, it depends on the items. There was a Christmas Eve showcase in the early 1980s that had a full-size airplane (i.e. the kind that requires a license to fly) for about $30,000. While inflation might have driven the price up to near $100,000 today, if you were to try to buy that plane today, it would cost you about $300,000. Almost all of that price increase was due to the skyrocketing cost in liability insurance for the plane manufacturer since then.
