For Megaman Battle Chip Challenge, several titles in the series use physical cartridges (chips) to boost your character's attack and other stats. Each chip contained a different stat or power, and sometimes even different characters. Each chip was sold separately or obtained through an arcade machine (the latter only available in Japan) and held a different value. They are still sold on ebay or other retailers, so prices can be found online. There are over 400 chips for each generation, three generations in total, so it gets a bit difficult to keep track of all of them.

Additionally, there were PET's that could be used as regular toys and didn't require the videogame, using the same chips and having the same effects, but in real life.

There is a Reddit thread that explains the whole chip stuff better and can be found here.

For example, for Pokemon card Charmander #44, the card was obtainable by purchasing the Obsidian Flames Elite Trainer Box. For Dondozo #12, the card was included with a checkout lane booster. It would be helpful for locating which product to buy to obtain the promo if said product is still available. Thanks! 

Export doesn't have date purchased but there is date entered which are 2 totally different things. I don't mind to have either both or at least replace date entered with date purchased as its the correct one.

On eBay there is an “item location” filter. Things very useful as prices can vary regionally. Having the option to filter estimated prices by region so it only takes into account, for example, items sold on eBay where the item location was “UK Only” would be superb.

I have a couple of of different folders that I use, but the one I use the most is a folder where I put the cards I collected in my childhood. There are literally thousands of cards, and I have to manually scroll and click each one into a folder. Maybe at the top of the page we could have a "move all button" for the cards that are not in a folder.

We look up individual comics all the time, and sometimes they are part of a lot of a collection. It would be beneficial to have a button for "add to lot" available right on the main result/details screen for a book. (Like "+wishlist" and "+collection")

Yes, we can add them from the lot page. But if we are identifying by picture we get to that details page first, so it'd be beneficial to cut out the extra step of recording the title and issue and then moving to the lot page to add it.

I mean u have NOK, our neighbor, why not add us :)

Please make it possible to add cases in stead of 6 loose boxes. Cases go for a premium.

I'm aware that there is an Asian English "region" for several consoles (PSP, PS3-5, PSVita, and Switch), however there are other consoles like the DS or the Wii with Korean games that are starting to show up on sites such as eBay. I think it would be really cool to see some of these games on this website.
