A cooler of shrimp headed for North Topsail Beach
Picture the sale you already make twenty times over on a July afternoon. A family stops on the way in, buys enough shrimp for the week, and gets back on the road toward the island. They are pleased, they are on vacation, and they are precisely the people who post about a trip. All of that goodwill goes nowhere, because by the time they think of it they are unpacking a rental and cannot remember what your place was called. A card in the bag fixes the timing. It gets scanned in the parking lot, or at the kitchen counter that night, and it opens your review page directly — no searching, no hunting for an account. Plenty of people will not bother. The ones who do are talking straight to the next family planning the same week, reading those exact reviews from a car six months out.
