It would be useful to be able to view the marketplace through the mobile app. I would especially be interested in features similar to the eBay mobile app. Mainly ones, such as getting a notification on my phone when an item sells. This would allow me to potentially ship sold items more quickly.

Let me see only listings with actual photos of the item instead of stock photos.

Your pricing on some rare games makes no sense - for instance Bang-O NEW sealed copy is less than a loose price. Obviously this makes no sense and your system should recognize this. Don't use any price would be better - although I found examples offered on games on Amazon. This is a bad flaw, and really hurts the credability of your site.

When filtering by Category = “Pokemon” and opening the “Set” filter dropdown list, the available sets to filter on still include sets which no longer have cards assigned to them. The options for this filter should only show sets still contained within a users collection and not include set previously in a users collection but have been fully removed/emptied since. Would make it much easier to identify which sets where in a collection currently. 

Hello will you be adding in garbage pail kids for 2025 such as battle of the bands Green Day and 40th Anniversary collection?

I'm starting to see these cards in shops around me now and have been collecting them for a while now and would like to be able to add them to my collection.

I’d like to sort my yugioh collection by percent of set completed to see where I am closest to completing a set.

PCG (Premier Card Grading) is becoming a widely recognised grading company in Oceania, particularly in New Zealand. While PSA currently dominates the global market (holding ~76% of grading submissions), alternative services like PCG are growing in popularity due to faster turnaround times and strong regional adoption.

Adding PCG grading alongside PSA, BGS, CGC, and SGC for price valuations would hugely benefit Oceania users and provide more accurate international coverage on PriceCharting.
