I am a little confused by your comment. You do not subscribe to any Apple services because you do not find them a good value but having never seen any value in them and never having tried them you would subscribe if they were sufficiently discounted?
How much of a discount are you hoping for, exactly? Is it realistic to believe that Apple is likely to offer a discount significant enough for you to consider subscribing to multiple services you currently do not see the value of? I fear you are going to be disappointed.
I suspect I am in for a disappointment as well as I do see value in several of the services and subscribe to Apple Music, iCloud, News+, and TV+ (admittedly for free but loving Mythic Quest, Little Voice, and Ted Lasso). I suspect any bundle I would get would have to include Arcade and I do not have any interest in that. That is pure speculation on my part and I might still be pleasantly surprised. For you, though, I see no hope.
