I asked the bungie store the same question, but it was led to here. The medallion pin discount code to be used at the Bungie store was not available. https://www.bungie.net/ja/Help/Article/47107 This help page states that the old code will expire. Reissued from bungie Rewards but the same code was sent by email. There are three discount codes that you want to be reissued or made available. :::WAYFARER SEAL COLLECTIBLE MEDALLION PIN :::DREDGEN SEAL COLLECTIBLE MEDALLION PIN :::CURSEBREAKER SEAL COLLECTIBLE MEDALLION PIN help me....
