You can split the oak again and that will hasten the drying, but getting some more dry wood is a good plan. At that price, if it's split and as advertised, you're stealing it. That's a great deal, even for a face cord. I think you should get at least 4 face cords though. Or a couple full cords. Just be sure it's really dry. Bring your splitter and the moisture meter and perform the same test and don't be afraid to walk away if it's not dry.
