You are correct, they don't expire. But if a TechNet member is caught selling or giving away keys or discs, that's the end of their membership. A quick $40 a pop isn't worth losing your membership over. As to the legal issues that's involved if a member is caught doing this, that's between the former member and his/her attorney. Because if you're physically caught (as in your hands cuffed behind your back) you're going to need one badly. Microsoft isn't going to allow someone to make a huge profit off of them and not go after them, if they can locate them. When you join, there's another EULA that you don't see on the visitors screen, when you pay, prior to them accepting your payment, you agree that Microsoft can hold you civilly AND criminally responsible for selling software & keys, among other agreements that you make with them. It is not permitted in your membership to be a broker for MS services, if that's what you're referring to.
BTW, my mom-in-law has been paid back, the only reason I asked her was I thought the memberships would be sold out before the date the promotion ended, she was paid back in less than a week, after my payday was deposited.
And another BTW, if I really wanted to make some BIG money, the retail value of the meds I'm prescribed monthly are over $4,000, and the street value is double that. But once again, the legal issues would be very severe if I were to be caught selling drugs, and most likely my doctor(s) (primary and PM) would consider that abusing the system. Abusing the policies, regardless of the services, will either leave you on the curb, or worse yet, the slammer.
My point is, it's best to play by the rules.
