Great suggestion.  I can definitely see the value in having that calculate and shown as a running total.

The request features forum is totally different from the website.  We don't really use the log in features on the request tool

This is already requested.

Database of Amiibo cards is here:

Cool idea.  I know what you mean about forgetting about a particular game after playing hundreds of them.  I'll see how popular this idea is before thinking more about the implementation.

Thanks for this suggestion.  We don't have that feature now, because people could have multiple copies of that game in their collection.  We don't know if that version was the one in their collection or a duplicate they are selling.  

At some point we plan to let people convert a collection item into a "for sale" item, and then those will automatically be removed.

I've added Nidoran.

I think all Mew #9 Promo cards are holo:

Please correct me if I am wrong.

All Base Set trainers and energy cards are shadowless so we don't have them listed separately.

This has been added now.

This will be searchable in the near future, but it was just recently added.  Our search index takes a while to update if that search term has already been stored.  If you search for "Killer Queen Black Pal" you will see it come up in the results.

Thank you so much for this very thorough information.  Very helpful.  I didn't even know those cards existed.  

I've made some notes on this feature and I'll wait to see how popular it is with other people before doing any work on it.  I'm guessing we would add other trading cards first like YuGiOh but it all depends on user demand.
