I always notice a lot of cards that get sold are still on the site, my guess is that there is no easy way for them to be removed?
Like it is not anything that will keep me from shopping at USL, obviously. I was just thinking, it looks better if everything online was available. (This does not included the drop down menus) Just talking singles.
Mercari, has a way to filter out the sold, maybe that can be an option for you.
Edge is one of my birthday buddies. If you had stocked up on some of the cards. I would see some future purchase. (Low end/Mid tier)
The other would be late 90's cards, insert from 1996 and through 2K. I missed out on a lot of those cards and they have the players I grew up with. So it may not hurt to have some of those in the store as well.
