Punchh allows for an administrative setting labeled "# of Processable Redemption Codes per Guest"
If the flag "Prevent guests from redeeming multiple times in one visit?" is not checked then the user can redeem multiple times on a single order.
This setting allows or disallows multiple redemption codes to be used on the same order during the same visit.
NOTE: This setting does not apply to Coupons or Promos
In order to change this setting, please contact your Customer Success Manager:
