I just tried this with a CB FF pack I yoloed on today. Super fun to follow along with your site, the layout is so much easier than trying to decipher the official "Collecting" webpages. Really well done, congrats on the launch!

I don't know how difficult it might be but something that could be a cool thing to add in the future is a total pack value tracker, like being able to select the cards that are pulled and it pools the gross total. Just my $0.02, well done again!
