Just to clarify.  You would like the Shopify integration to be able to add products from PriceCharting database to the store's Shopify database and then price update from that?  

That might work really well for a new store without a database.

Thank you for this detailed bug report.  I will look into this and see about a fix.  

Closing.  We are including CGC 10 price point and CGC sales in other grades too.

You should see an up or down arrow next to the price for all items in a collection.  We do not show how much collection item values have changed, but we will indicate if the price increased or decreased recently.  Please let me know if you are not seeing that, or if you want to see the actual value change next to each item.

Thanks for this comment.  Very cool idea.  Is that app that does it already, TCGPlayer or another app?  How do they handle variants like holo, 1st edition, etc.  Does the app recognize those differences and provide accurate value?

Sorry for any problem.  Can you give me some examples of incorrect prices?  I will look into this ASAP.

Thanks for those thoughts.  I can see some value to tracking games owned across platforms and physical and digital all in one place.  We are focused on physical collectibles at this time though.  This is a possibility in the future, but not something we have any immediate plans for.
