Piggly Wiggly?

Kenyon and I are driving through the State of North Carolina toward the beach. I'm looking forward to a week of relaxation. On our way we passed through a little town called Plymouth. I saw a Piggly Wiggly. I've only heard of these. Like my mom shopping there as a young girl, or the lady from Driving Miss Daisy driving herself to the Piggly Wiggly. I haven't seen one myself (that I can recall). I thought they'd all gone out of business...until today. Is this the only Piggly Wiggly or are there others? Why did they go away?
