MindfulMrs sez, people today have no idea what a grocer's was like in the 1950s, even, much less the 1850s. Pickle barrel? Ewwww.

Fast transport is a big factor, and refrigeration also, but the sealed, airtight package can make both moot, and otherwise extends storage and preserves quality.

I could do with something easier to open with hard plastic cases sometimes.
