Putting a pricing page up was almost certainly an extremely bad idea.

By putting the pricing page up you moved yourself out of the "hey I'm just a fan it's just fan fiction" category and into the "unlicensed commercial use of a registered trademark category." The later is a much more serious category to put oneself in, and involves a much more serious set of lawyers than the bots who send out cease-and-desist and takedown letters.

Removing the pricing page will not make the fact that you had shown a pricing page go away.

IANAL but I'd take the site down very quickly and never put it back up again. Just receiving a letter from one of the brand's many law firms will almost certainly end up costing you thousands of dollars drafting an appropriate response in hopes that it doesn't escalate. You really don't want that to happen.
