TBH I just filled out forms today, and struggled. Yes they have a "search function" but my issue with a "mark jewelers" wasn't an "option" and after selecting the comic there was no where to write it.
Anyhoo, I refilled it out, and clicked the "can't find my comic" link on the form to add: the issue with the Mark Jeweler note in the "variant slot"....
UF4 shouldn't be "that complicated" but given the issue, the hired authority to slab books should gain knowledge enough when receiving books, that it shouldn't get so far in the process, sometimes, for it to be a Grader issue idk food for thought
