We offer a "notes" and a "description" section.  Typically the "notes" section would hold information like this or any other noteworthy thing about the game contents.  "Expansion pak included in original packaging", "1000 produced", etc.

Please use the "notes" section to add any information like this for special editions.  You can also use the extra photos section to post photos of special editions contents.  Quite a few items on the site have those extra photos for that special edition stuff.

I'm not sure I understand the question.  What url on the site (or tool) are you trying to use the PriceCharing ID or TCG ID?  Are you wanting to search for those IDs or see what those IDs are for different items?

Can you link me to the information about this set and/or the checklist?  I'll look to add this.

Do you have a link to the full checklist somewhere?  I can definitely look into adding those, but it sounds like you know about the full checklist so that would be a very helpful reference.

Thank you.  So glad to hear your like the site.

You can share the collection anywhere with the link provided on your collection page.  

Are you looking for ways to allow people to find your collection on PriceCharting itself?  

Thanks for the suggestion.  Right now we do not keep track of any bonuses that might be included outside the retail packaging.  We consider that memorabilia and not something we track at this time.  If the pack-in was sealed in the package (like a music CD for pre-orders or something similar) then we do track that on the site.

I'm leaving this open to hear other people's input, but that is our policy right now.

Can you send me a photo of the box you received?  If it is sealed by Nintendo and clear that it is their seal and not a generic one, than I think that would be considered new.

Yep, Blagblare is correct.  We do have a mobile web app.  You can read latest info on it here too:

I'd love to hear your feedback on this after trying it out.
