A Pink Hill feed and supply counter, one season of cards
Picture a counter that serves the same growers every week and has never once collected a review. You put a small card by the register — not a sign, a card the clerk hands over with the receipt. One line of text and a code that opens your review page directly, no searching, no app. Run a season of transactions, and a fraction of them scan it, and by the end of the year you have a public record where there was none. The cards cost almost nothing and the code stays yours: when you want it pointing at a spring price sheet instead, we change the destination and every card already printed keeps working. Nothing has to get reprinted, and nobody working the counter has to remember a new script.
