I currently can't use the discount code that I had claimed pre February 28th. I am now trying to purchase these medallions but the code that shows up keeps saying it is invalid and I can't make the purchase. I think I may need a new code as I had claimed it before the date and now the code has expired even though now it has been extended. According the TWAB and support article I should consult the forums here. "If a code expires and players are unable to use a code on the Bungie Store in time, they should make a post on the #Help forums describing the issue for assistance."
