Need help on ps plus subscription

So hey guys, I have order ps5 on Amazon (dual controller bundle). Original cost was 58k, I have applied emi for 18months, 3.4k per month with 4k credit card discount. Now I saw discount on ps plus deluxe subscription. My console will be delivered on Feb 27, but the subscription discount ends on feb26th. Can I buy the subscription now without console?? Is that fine?? I have given my personal mail id for sign in playstation, I will be using the same mail for console. Can I buy the subscription now??
