I have been spammed recently by an offer saying if i buy 75 keys I will get 75 free, I hid it yesterday because it was annoying on every log in however I have decided I want to use it now. But now I can't find it.
If it is still active start the process of purchasing keys, it should say in parenthesis the special offer when you pick the different key options. If you do not see anything in parentheses then it probably expired.
Good luck._.•´¯`•._.•´¯`•.* D E L A Y *.•´¯`•._.•´¯`•._
