When choosing payment against delivery, you must take into account the following conditions:
1. We may call to confirm your order. Please make sure the phone number you provide is correct.
2. If you are not in that moment, another person will be able to receive the product as long as it has the money and has an official identification.
3. You must have the exact amount of money to pay for your order, since our messengers do not carry change.
