A faster alternative to a paper tally if you want one — keep this open at your register and tap it each time a customer redeems your HOMERUNYEP offer. Totally optional; plenty of merchants prefer paper, or their own POS's built-in promo code, and that works just as well.
Where this data lives: right now, counts stay in this browser on this device only — HOMERUNYEP doesn't see them. This is a convenience for your own records, not (yet) a live feed back to us. If you want a shared count across registers or devices, that needs a small backend we haven't built yet.
