You don't care for substantial discounts and free games? Why?!
Long story short: I don't want to pay extra for online when it should be INCLUDED when you buy a console.
As for discounts, they are substantial WITHOUT PS plus too. On some occasions you get a better deal with PS Plus but if you wait a bit longer that "better" price is the next sales promotion for everyone and not just PS Plus members.
As for free games, they are not free as you must pay for PS Plus and the moment you quit your subscription you don't have access to the so called free games you chose when you were a member.
