SPLaterpay.callback.hasAccess();
$('.lp_mwi_payment-method-wrapper').parent().parent().hide();
$('.deobfuscated-content').parent().removeClass();

Well, that's really OVERKILL, lol
Good Job. That's way simpler than our solution. I will update our code, if you permit it.

Why not just use GreaseMonkey? Prepend this code to @RROrg's script, and you're set:

// ==UserScript==
// @name      Spiegel Plus
// @namespace *
// @include http://www.spiegel.de/*/*
