For future applicants with the same question reading this thread, yes, while it costs money to withhold one of your AP scores when you send them via the College Board, it does not cost any money to completely delete the score (which is permanent.) However, you should only do so if you get below a 3 (and maybe not even then, as some schools will give placement, even if not credit for a 2 like UW.)
Note: There’s a specific deadline every year to cancel a score if you chose to use your one free score send and don’t want that score sent to that college, however, you can always cancel scores at any time (unless they’re archived, which happens when your most recent AP exam was 4+ years ago.)
