Match lowest price option
It is a hassle, especially if you have many items, to know whether your listed prices are in line with others who might also be selling the same game(s). An example is Amazon's "Match lowest Price" option for sellers. It keeps prices in check while also helping to curb artificially inflating game values.
Messaging system via website
We need to be able to communicate directly through the website. The e-mail messaging system gets lost with the hundreds of other e-mails I recieve. Plus it'd be a lot easier to organize and go through the messages and whatnot
Add marketplace features to the current PriceCharting mobile app
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.
Filter marketplace listings to see only those with photos
Let me see only listings with actual photos of the item instead of stock photos.
Fix the NEW Sealed $ = it is lower than "loose" in Dreamcast
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.
We are monitoring prices on a daily basis to remove junk listings (the root cause) and fix price inversions like you mentioned. We want to fix these whenever possible.
Tig makes a very good point though about games with old sales data.
The last sale might have been years ago. We can either use that as the price, or we can extrapolate how much the game might be worth today instead. The 2nd option is fraught with inaccuracies so we decided to go with option 1 and show users the sales history.
Create Single Value and Total Value Sortable Columns
Having multiple cards in my collection, the total value of all cards are reflected as Value. Create two columns titled: Individual Value and Total Value. This would assist is assessing and sorting the cards by individual values vs total value which gets murky when comparing 1 card’s value to the value of 6 cards
Disney Pins
Please add a category for disney pins. There is a very large community that has been around for 25+ years. Some pins have valuations in the thousands and there are lots of transactions that occur through eBay. There is no pin trading collection tracker (with price tracking). Having this available would be game-changing for the scene and be an instant hit.
Add option to increase count on existing collection when adding duplicate cards per folder
I track all my duplicate cards in a duplicates folder. This works great until I go to add more copies. I would absolutely love the option to increase the count of pre-existing copies rather than creating a new entry in my collection.
Change Coins To Currency
By changing "coins" to "Currency" you could include coins and dollars, along with coins and dollars from around the world. along with things like silver + gold
