Solved
Attempted to buy Raddus LSB and got an error (webstore)
Tried multiple times on multiple devices and browsers for webstore per customer support chat. Nothing worked and they directed me here. Able to purchase other items, it's just this bundle that's affected.
I was able to fix this. Went into the app to try to purchase the bundle. It said the purchase was pending and I canceled it. Then I tried again via web store and it worked.
