9th visit free — and the calendar fills itself
Three barbers, one shop in central Lodz. The stamp card turned "I'll come sometime" into "I have to be back Friday".
The challenge
Classic — a premium barber shop in central Lodz. Three barbers, private chairs, prices $20–30. Regulars come every 4–6 weeks, but Marek (the owner) knew some "forget" and only return after 8–10 weeks. The calendar had gaps mid-week.
Rollout
A stamp card: 8 visits, the 9th free (worth ~$25). Key push: "Time for a cut" — sent automatically 28 days after the last visit with a booking link.
The surprise
Customers don't respond to "you have X stamps". They respond to "it's been 4 weeks since your cut — your office mates have noticed".
