You’re unwilling to have good credit? That’s all it takes to qualify.
Speaking only for myself…If I were to go to Apple they would ask me for the entire price of the phone up front.
My carrier offers leasing or installments.
Apple does too, but then I'd have to qualify for their program. Most likely not going to happen.
And I'm unwilling to do what it takes to qualify for that when Apple doesn't offer phones I want to buy (since the iPhone 5).
