  4. When am I charged processing fees?

    You are charged when the cards are deposited into your COMC account.
  5. What is accepted through a COMC Mailbox?

    Trading card singles only (this does not mean only 1 card at a time).
  6. Once the cards are in my account, what can I do with them?

    You can sell them on COMC.com by pricing them for sale or mark them for shipment to your home. You must have sufficient funds in your account to pay for shipping. Cards processed through your Mailbox do not qualify for flat rate shipping. These cards will be subject to per item S&H.
  7. What about bonus cards from the 3rd party sellers?

    We will process ALL such cards that come in under your name at regular Mailbox processing rates. It is your responsibility to urge your sellers to either not send bonus cards or mark them with a big X to signify they are just spacers or packing material. However, please remember: you have a COMC account and are able to price any unwanted cards for sale on the site.

  8. What about base cards from a group/case break?

    We will process ALL such cards that come in under your name at regular Mailbox processing rates. It is your responsibility to urge your breakers to only send the cards you want us to process. Some breakers don't send base cards at all. However, please remember: you have a COMC account and are able to price any unwanted cards for sale on the site.

  9. How do I let a sender know to not send me extra cards?

    Here is an example of what to say provide to your sellers. "This order is being sent to my COMC mailbox, and I am charged a per item fee. Please do not include bonus cards in this shipment. If you use extra cards as spacers or packing materials, please mark them with a big X so they are not processed."
  10. What happens if one of my cards is shipped by the seller but never arrives at COMC?

    That is between you and the seller. COMC is not responsible in this case.
  11. What happens if tracking information indicates the package was delivered to COMC but I get no confirming email and picture?

    This probably means the package address included no specific username or the username was misspelled. Contact Customer Service with the specifics of the card, including tracking number and estimated delivery date
  12. How do I file a complaint or dispute a charge?

  13. What happens if I forget to change my PayPal address when ordering something other than a card and it arrives at COMC, addressed to my Mailbox?

    You will be charged a $10 fee for the handling of anything not normally accepted through the Mailbox service. Also, you are responsible for any additional shipping costs associated with returning the item to you.
  14. What if the 3rd party seller sends the wrong card?

    You need to contact the seller to make arrangements to correct the situation. We can ship the card back to the seller, charging your account for the shipping fee.
  15. What if a card I do not recognize as mine ends up in my account?

    If you suspect an error was made, please contact Customer Service with the details so that we may investigate the issue. Please do not list the card for sale or mark it for shipment to yourself.
  16. Do you accept Panini Points cards?

    No, we do not because we can not verify whether they have been used already.
  17. Why use COMC Mailbox in Canada?

    1. Save on shipping. Postage within Canada is less than to the United States. Sellers often pass these costs to the purchaser. Over time, these savings can be of significant benefit to the buyer.

    2. Items are in transit for less time, reducing risk. Shipping within Canada typically is 5 business days or less. Shipping to the United States can take up to 3 weeks. Packages will also not be held up in customs. You can minimize the loss of a package in transit if it gets from point A to point B the fastest time possible.
