*** NOTE: I've stopped updating this app. Rather than remove it completely, I've decided to just make it free. The downside to this is that there are only older card sets. Also, if anything breaks, I probably won't fix it. Too hard to keep this up-to-date with so few users. Thanks to all of those who supported this app.
This is the only app you'll ever need to make sure you're making great trades in Cardfight Vanguard. With this app, you will enter card names and add them to one of two lists. When you add it to a list, the price is fetched automatically from TCGPlayer.com. The total value of each list is clearly provided so you know how much you are trading away and how much you are getting back. It's that simple!
You know that one bad trade could be WAY more costly than this app, so I hope you'll give it a try and feel safe in your Cardfight Vanguard trading!
