Paste the text with codes in the input box and hit one of the buttons.
Submit Codes: try out each yum code until a good one is found. You still need to click the "Redeem" button on the Bandcamp page to proceed to the download page.
Purge Codes: try all codes and remove the used ones. The final list will only show yum codes still available to redeem.
