I think comparing Matsushita and Hostess is like comparing apples and oranges. I mean their circumstances could be similar but I can’t tell from the information you provided.
The example applies even better to Hostess. They make a consumable snack which almost everybody eats. If you already have a nice radio, you are less likely to barter away groceries for a radio than for snacks with a shelf life at least as long as the radio.
