Okay, I successfully canceled Black Sabbath LP. Then I successfully canceled the subscription entirely. Then I resubscribed to the subscription to see if that would generate a new selection for this month. Now I'm refreshing the "Your Orders" page to see if anything appears, but so far there's nothing. I wonder if I've "missed the window" for getting anything this month? According to the subscription page, "Your subscription will renew at $24.99/box plus tax on the next order date July 14, 2021." I'll post an update if a new title appears in my orders, but for now it appears that my experiment above just resulted in skipping me for June.
