That is a good idea.  This capability is already available for the Lot Automator.

If that tool works for your exact use case, then you can store the values for 30 days.  

Users can click "report" link next to any sale on the site and report this to admin and contributing users.  Contributors can use a page like this:

And review reported sales too.

We plan to add something like this in the near future.

You can start selling and read more about it here:

We consider this memorabilia and not something we track on the site.  Generally speaking, the item needs to attach to the video game system or directly interact with the system for us to add it.  Games, controllers, most accessories are fine.  An Xbox poster would not be.  PS4 neon sign would not be.  I hope that makes sense.

Can you give me more information about this feature request?

Thank you.  I've combined this and used the page with the UPC and more data, but changed the name to Tekkaman Blade since that is the English name written on the game.

What exactly is the problem or error you get?

I’ve heard a couple other people with this issue and it is something with Paypal and their browser cache. The easiest way to fix it is using a different browser. That has solve the problem for the other users.

You can also clear the browser cache on your current browser, but I personally find it easier to just use a new browser for this one task.

I hope this helps.

We lump all PAL games into one category.  We do not track each country separately.  You can use the PAL versions we have on the site for your collection and definitely add any missing Australian exclusive releases we might be missing.

Thanks for that feedback.  

You can store the value of items for a particular console.  If you filter your collection to a specific console you will see the summary data about that particular one only.  Here is an example from admin account.

Example collection filtered to SNES only

You might look at the Lot Automater tool too.  That does the import/valuation thing for you but it doesn't require the collection tool and deleting and importing again.  You can save each list for 30 days and do as many as you like too.  The full tool requires a $6/month subscription but that could save you quite a bit of time depending on how often you do this.
