No update.  Mercari has not been forthcoming with the data we need to make this happen.  I will talk with biz development person here to see if they can reach out again.

Done.  Please leave the card number off of the name field.  That should only be entered in the card number field.

Please explain how the cards are organized.  I see card numbers like YH-F02-002 and YH-T03-003

But I also see Moon Edition, Rainbow Edition, etc.  

This will help me make sure I add these cards correctly.

Please upload a photo or a url to these items so we can add the missing items.

Sorry, it takes about 24 hours for a set to show up on the set lists.  You should see it now with "pokemon x oreo" name

Sorry for any problem. I've asked servers to revalue and recount everything. That should be done by the time you get this, but sometimes takes longer on really big collections. Sorry for any inconvenience.

I added that set.

I couldn't find any checklists with the card numbers, so for now, users can add any missing cards to this set.

Thanks for reaching out. I've added that set to our list of sets to add. We will add that full list in the next few days.

I've added that set now.  They will show up in about 24 hours.
