So the general consensus on Listia seems to be: no consensus. I myself can't decide if I like it or not, although my recent experiences have all be great. Several of my first transactions had, shall we say, issues, and left a bad taste in my mouth.
But I've been feeling better about Listia lately. I think with a little luck and some good strategy, you can make out well on Listia.
Case in point- a few weeks ago I "sold" a Yasiel Puig 1971 mini card for 4,000+ points. I was extremely please to get that much for it, and I think my timing for selling it was good.
I spent those 4,000+ points on a couple of cards that came in this week. The first is a card I've wanted for a while:
This manu patch card of Razorback Legend Darren McFadden is mega cool, dude. If I were just making trades, I would have gladly given up the Puig for it alone. Instead, it cost me 2,600 points. With my remaining points I was able to get a card of another 2013 hot rookie:
This is some kind of "Father's Day" promo card, but I don't know (or care) the story behind the promotion. I'm just happy to get a numbered card of Myers..... WHO I'VE BEEN ON A BASEBALL FIELD WITH!!!! I would have taken this card straight up for the Puig as well.
