Hello!
Just wanted to take a quick second to apologize for the long delays/ no responses in trade requests I've received. In January this year I started exploring NFTs and learning a little more about investing/ selling cards and collecting PC cards that have the potential to hold more value for when I eventually pass them onto my kids.
I ended up going down a pretty big rabbit hole and eventually stumbled upon a startup project called Collectorz Club. Essentially, it's a project aimed at creating a network of cards shop owners (physical and online) to expand the hobby into the digital world of NFTs. Among many, many things, the project is working on is a marketplace to buy and sell cards as an alternative to eBay/ COMC/ etc. The marketplace itself just launched within the last month, so it's still in the early stages of growing and attracting an audience, but it's got a nice, intuitive layout and has about half the fees of selling on eBay.
I know NFTs are not everyone's cup of tea. However, I know a lot of people on here also sell a fair amount of cards, so I figured I would put this plug out there in case anyone is interested. Basically, you can buy one of the NFTs to gain access to selling on the marketplace. There is a long list of other benefits (including daily giveaways, free chances at getting in a break every month), but the marketplace seems the most relevant to users here.

If you are interested in learning more, I would encourage you to come check out the group in Discord (https://discord.gg/collectorzclub). I'll add that, since getting back into collecting in 2020, this has been a top resource alongside TCDB itself in helping me learn more about card collecting and finding ways to keep the hobby personally affordable. I am now currently a Mod in the discord chat and would be happy to help answer any questions or explain things further to anyone interested.
