Do I pay for an order in a Partnered Merchant? Udi Oster December 15, 2016 19:36 DO NOT pay for your order with the PEX card. The order has already been paid for. Exception: CHIPOTLE - order will be marked “PAID” so you’ll know it’s being prepared BUT you’ll need to pay at the cashier with the PEX card for the order.
