Search in ebay using "D&D Fortune feywild". I think both Auggies and Troll & Toad sell them from their non-ebay sites also. Well, maybe not Feywild yet, but they have the two older sets.
Cheers. Not much luck with the ones I'm missing, unfortunately. Ebay looks like the way to go though. The "collectible" nature is annoying as a completionist. :(
