A PEX card works like a debit card and is provided to the Courier by the Company in order to pay for orders from certain merchants (non-partnered). If an order shows a "paid" designation within the App, you DO NOT need to pay for it (the order is with a "partnered merchant" and they have received the order and it is already paid for). If the "paid" designation is not shown, then the order requires the Courier to place the order and pay for it via PEX card. PEX cards are assigned funds for use at the specific merchant for the amount based on items ordered. It is important to carefully place the order for correct items so that the card is not declined.
