Ric Flair and Ring of Honor

Flair's people had talks with ROH about him making an appearance on a Big Show, but the price wasn't feasible for ROH. Flair has an appearance fee for coming in as well as a separate fee for doing autographs. On top of that, he also has a separate price for coming into the ring and cutting a promo.
