Thanks for that feedback.  I'll look into this more. It might be easier to streamline the photo submission tool a bit to make that faster, but a scanner could be possible too.

So this would be like the photo tool we have now but streamlined because you would just scan the photo automatically and determine the card instead of needing to submit the photo?

I have a developer looking into ways to improve this tool.  It works well for most users, so I'm sorry you don't have success with it.  These intermittent errors can be tricky to troubleshoot.

We don't really authenticate items.  That is the job of a grading service.  We will let users know if they are selling a fake card, but error authentication is not something we specialize in at all.

Cool idea.  I can see that value in that for older items.  I'll have to see how popular this is before doing any work on it because it would take quite a bit of development and resources to store all of those images.  But it could be valuable too.

We used to track DVD prices years ago, but it was not popular.  We closed it down.

We are hoping to implement "folders" for this.  You can move items to a particular folder to organize them more if you want.  You will be able to name the folders too, "sell", "bad condition", "needs manual", what you want.

Do you think that would work for you?

No immediate plans to accept other payment methods.  You can use credit card during Paypal payment if desired.  The marketplace is not a focus of ours on the site at this time so we are spending development efforts in other locations.

You can do this now with search results or collections.

In search:

Choose "Filter by Console" or "Filter by Set" drop down (exact wording depends on the results).

And choose the set you want.

In collection:

Filter by the category first (pokemon, video games, etc)

Then choose "Filter by Set" from that list.
