Hi there.  I would love to see advanced filter options, so that I can pin point specific games in my collection that are missing items to start making lists to obtain them.

Instead of just 'Include only', I would suggest and advanced filter option in addition to this which would allow you to include or not include any of the options, perhaps by check box.

This would allow us to see which games are needing items to be CIB, but may have a box, or manual, or game, and any combo,  Or all games that are CIB and sealed.

Some Neo Geo MVS were never released for AES systems, so people started swapping chips between the wanted MVS board and a cheaper, usually early title, AES board.

The resulting convert is a playable MVS game on an AES system, since the only difference between the two cartridfes type is the pcb thickness if im not mistaken.

The leftover MVS cart is also playable on it's corresponding console, the game being the AES swapped one.

Nothing else is changed or added, every piece is SNK original and playable on original software.

Would be great to see the list of consoles in the filter tool for hottest item as many of us only deal in certain systems and seeing the movement for those systems specifically is valuable.  ESP when sometimes only 4-6 games show up in the list because of how many different systems there are. 

Noticed a bug with the Yu-Gi-Oh collection accounting system. I did not want to keep track of my card collection anymore and focus on video games, so I went and clicked REMOVE with all of my card entries. The issue is, while it currently says I have no Yu-Gi-Oh cards in my collection, it also did NOT remove the multiples of cards I had, so I simultaneously have 0 cards, and 7 cards worth $16 in my collection. 

Seems to be a bug.

Add the ability to buy and sell Magic the Gathering, Pokemon, et al to the marketplace.  Please ^.^

If there are multiple listings for the same item, allow users to suggest a merge. For instance, currently there are two listings for the same GBA SP console. One is incorrectly listed as "black" and one as the Nintendo color "graphite." In addition to having the wrong name, the "black" one seems to pick up a lot of prices for other system colors since there is no actual black color. 

You have the Hori controller for the GameCube but not the N64.

Read the sold listings on a grey n64. Most of them are funtastic and things like bags, making a very inaccurate price thats obviously effecting ebay prices. Its like this for most consoles on pricecharting. I click edit to remove them and you dont remove. I try to edit and fix these consoles that include the wrong items but my edits dont go through or no ones checking them. Basically every console is like this, which drives up the price on the regular consoles. Since its combining prices from much more expensive colours or variants of the console. Other times it shows wii's in gamecubes, and 360's in OG xbox..
