Update 5/7/20: It took a couple of extra weeks than expected, but Neiman Marcus has now filed for bankruptcy.
Reuters is reporting that Neiman Marcus is likely filing for bankruptcy protection this week. I don’t believe that would make Neiman Marcus gift cards worthless immediately, but it’s obviously not a good sign. This therefore isn’t a gift card brand you want large exposure to right now.
As things stand, GiftCardMall is still offering a 15% discount on Neiman Marcus gift cards, but that’s far too much risk for my tastes right now, especially seeing as those are physical gift cards which you’ll have to wait to arrive, increasing your risk that they’ll become worthless by the time you’re able to resell them.
