This here is a area where you can forge deals with cards, I came up with the idea with this from Roblox forums back then and just didn't see that much specific broad trading areas.
Don't scam or you will be listed on a factbook if there isn't repercussions.
Also put your offers and looking for cards here, if you are selling or buying, then carry your business to telegram.
Telegram me if you have issues or you need to report scammers.
PLEASE DO NOT DO DEALS HERE, DO THEM ON TELEGRAMS, JUST PUT OFFERS HERE.
