Collectors typically don't include homebrew and prototype releases in the definition of a complete collection, so their presence in the price list makes it very difficult to see the state of one's collection. Being able to filter out these kinds of releases would allow completionists to see a satisfying page full of orange "In Collection" icons, or be able to easily pick out the games they're missing. 

Sort by items you have more then 1 of so I can see which items are duplicates

Many times I buy a big lot and I want to enter the value for everything. Once entered I want to see if it's in my collection and I want to be able to add to my collection from the lot value collector.

I only use PriceCharting for tracking my video game collection! It’s an amazing resource. I would love to see you begin tracking Garbage Pail Kids cards. While my collection is very large, I have no good way to track everything. That would be a great addition!  Thanks 

Exclude My Collection from Buy page and Games list

I would like to exclude any games already in my collection when I browse the Buy page and a Games list page.

My two use cases:

Show me all <system> games for sale that I don't currently own on

https://www.pricecharting.com/search-products?q=&sort=name&console-uid=G17&genre-name=®ion-name=all&exclude-variants=false&stock=in

Show me all games in the Games list that I don't currently own on

https://www.pricecharting.com/console/nes

It's currently only possible for missing items within system categories to be added, it'd be helpful to also add the missing consoles/systems too such as the Apple Bandai Pippin.

Could we get a category for inserts? Things like posters, maps, registration cards, safety instructions, promo ads, collectibles (ex: yugioh cards bundled with game), etc. There really is no database which keeps track of what games have what inserts, and a game really isn't truly CIB unless it has them.

I'd go so far as to remove the 'manual' category and replace it with inserts and make manuals another insert.

I just want to see which game has gone up and down in value like the Amazon cart

The prices can vary substantially across europe depending on the languages on the covers in but as things are now all games are all bundled up under pal and are not country specific. This would be a great help for users accross europe as the priceswould truly reflect their location instead of a european average.

I'd like to combine the ebay lot bot with the game sniper to constantly keep an eye out for titles I'm hunting for. The game sniper is ok if you want to blindly buy random games that show up at a discount but I'm looking for specific titles and want it to find them weather they are in a lot or sold individually. I'd also like this to be able to run without the need to keep it running on my computer and have the system email me when there is a listing. Some titles wont show up for months and I don't want to miss them.
