The Big Bad store is out of everything, as usual. Damn it, I want a blue Ghost Rider! It sure is hard to find for the "non-variant" version.
That's the question, isn't it. I'd say Amazon, but they only have scalper-priced ones right now. They could always get more in of their own stock, which is usually at MSRP. But you'd have to watch it like a hawk, or better yet set a price tracker on the figure and hope for the best. Just google amazon price tracker and you can find some service that you can set up.
However, the only mostly-reliable way to get ML or DCUC for around retail is to find it at retail or preorder by the set or the case. It's a sucky situation.
