DocSwag I just realized I have a coupon for 50% off Civ VI Deluxe. The question is, do I buy it or do I not? vanished does it expire? Does it stack with sales? If the answers are no, and yes, then wait until the game is like 50% off and then use that too so it's 75% off in total. October 19, 2017 DocSwag It expires in 11 days . I'm not sure about sales but I think it does? October 19, 2017
