We have those games here:

https://www.pricecharting.com/console/jaguar-cd

If you search for these games they should show up too.  "Myst jaguar cd" for example should pull up the correct game.

Downloading the CSV with all of the items and then sorting that CSV based on the unique ID (column A) will give you the sequential order in which items were added.  You can then keep track of the last number you added and next time when you download again, you can start from that number and add the new ones.

I hope that helps.

Added.

I definitely want to look into this.  Can you give me a link to the page on the site with some of these sales or links to eBay sales that are mis-categorized on our site?  I want to make sure any of these are addressed and the root problems fixed too.

We plan to add this in the near future.

You can copy the url where you view your collection and share that with other users.  There is also a "share it" feature on the collection page too.  Click that and you will see the url to share with other people so they can see what you own.

Thanks for this input.  An "add another" option under "in collection" would probably work well.  Sort of like the drop down we have for "+Collection".  

I've made a note about this and hopefully we can add something like that in the future.

Thanks for that feedback. That is a feature we want to add in the next update. I don't have an exact time frame for it, but it is the highest one on our list to add. Stay tuned.

Sounds great.  Thanks for any contributions you can make in the future.  Good luck with school (I assume based on your schedule)

Can you show me a screenshot of what you are seeing?  I definitely want to fix this but I need to see the page you are looking at to fix it.  Thank you
