When I first arrived in the DAFW area, I quickly learned which grocery stores featured “discount card” systems (Kroger and Tom Thumb) and which don’t. You know the ones–where customers are expected to carry a little card around with them that qualifies them for certain lower prices. Those who don’t carry the cards end up paying significantly higher prices. I suppose the cards are intended to induce customery loyalty. And so they do. I’m very loyal to the stores that don’t have them.
