I bid on tickets for the a Minnesota Twins vs Colorado Rockies game, and it went well and was actually a little fun. I bid for two tickets - once I put my tickets and corresponding section, it told me roughly how likely I was to get the tickets. Then I pressed the button, and right away it told me my bid was successful!
Also, there were no fees at all, which was pretty nice, because those have a tendency to gouge you! Just for fun, I compared my tickets and pricing to stubhub, and my tickets were cheaper than they would have been on stubhub for that particular area. So, I would recommend trying out ScoreBig, and I will likely try it out again. I can't speak to their amount of tickets or ubiquity of events, but I can say that my experience was a successful one!
