Add “include only” filter to the marketplace
Some of the games in my collection I need just the box or just the manual to complete, would be nice if in the marketplace there was an “include only” filter like in my collection to view listings for a specific combination of box, manual, or game.

You can filter by "includes only" in the marketplace. Here is a page showing that with all active listings.
here is a result for one particular game:
https://www.pricecharting.com/offers?product=6528&condition-id=7&status=available
You set the "include only" for any page using the "Sort/Filter" box.

Market place: Search by CIB
It would be nice to have a feature in the market place to filter listings by loose, game/manual, box, CIB, New

You can already do this. Here is a link to a page showing it:
You need to choose "Includes Only" option in the "Filter Results" section.

Default chart (CIB if disc based, loose if cartridge)
Currently the historical chart defaults to loose, which is great for cartridges, but for any disc based system it'd be cool if it defaulted to CIB, since the first thing I always do is toggle to that.

Pokemon Booster Box Pricing
Add pokemon booster box sales to the sets. I would love to see the valuation of each booster box over time.

Closing. We should have booster boxes and booster packs for every Pokemon set now.

Support Quantity Option for Collections
Instead of adding multiple of the same game/card in my collection add a quantity field so I can include multiple copies that way. Then calculate the total value based on the quantity.
