Running a giveaway or promo? Use the Free / ₱0 button to record a mine without stamping a price. The label still prints and the buyer still appears on the mine board — the mine is just marked as free.
When a buyer mines a free or promo item, their name appears on the mine board as usual.
Click the Free button (or press 0 on the keyboard) to stamp ₱0 on their row. No price is printed on the label.
Press Enter to print. The label prints with the buyer's name and session info, but without a price amount. The row is marked as free in the session record.
