How long will they last? I mean if I activate them after one year, will they get expired or still be working?
Those are non account keys, if you formatted your PC without deactivating the key first your key will get locked permanently since it does not come with account access.
I am selling keys with account access if anyone interested for just $10.
Don't promote your stuff in my Thread, especially when I can sell full access accounts for $2 a 80% cut from your price, if anyone wants a Full Access account if you feel it's important just open a Message on my Selly Page.
