When I need to change a price or take an item down, it would be helpful for game names to be in alphabetical order, so I dont' have search through several pages of listings to find the item.

There are huge discrepancies between game prices. I've see some games, in the same condition, have a $20 difference in price. And, unfortunately, there is no easy way for sellers to adjust for this. I would normally adjust my prices on a daily basis to be one of the lowest available on the Marketplace. Last week when I adjusted my prices, it took me hours to do so (I have many items). A week later many of my prices are no longer competitive, but I just don't have the time to go through each and every item on my list, see what others are charging, and adjust my items accordingly. We need a more streamlined way to manage our inventory. This is resulting in lost sales.

Maybe you can add a "Last updated by User Name" and a total count of updated records by that user for some recognition to those who contribute to the site by adding and editing all the item details and photos. Just a thought. Thanks!

Allow imports by PSA certification number to allow easy mass import of collection. Use PSA API to look up the Card and Grade and add to collection automatically without having to add extra description of the card

It would be extremely helpful if both on the app and website if you could check box tool to be able to catalog large batches of cards at once. Every website uses this feature Email servers are a prime example.  It takes so ungodly long to click each dropdown.  Not to be to rude but its a basic feature that should have never been over looked.  when you have large amounts of cards like I do.  I sometimes need to change folders and this makes it nearly impossible as it is.

CGC grades go in increments of 0.5 up to 10, then have Pristine 10 and Perfect 10. Pristine 10 is tracked but Perfect 10 is not.
