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.

I see we now have the option to add Ebay sales. Would it be possible to add Heritage Auction sales as well? There are a few items that weren't added until after the sales happened, and they're rare enough that no sales have been registered since. 

Please add support for CGC half grades (0.5 increments) for comic books.  At least add 8.5.

The price difference of a half grade can be significant.

They are some quality cards and have great artwork.
