I see something about this in the “Installing & Authorizing Eventide Plug-ins” Post.   “If you bought the plugin on eventideaudio.com, you do receive everything immediately after payment, but sales that go through eventidestore.com are processed by our front office and therefore aren’t immediate. “  Strange that there are two stores (is this still true?).  A note in the reciept would prevent me form going around in circles trying to authorize.
