Ive been wondering about this for a while so I'm finally just going to ask on behalf of all the other playstation plus users, are we able to purchase another year of playstation plus and have the time added on to the end of our current remaining time. There seem to have been a few deals on it since I got it but I have never tried to add more time because I'm not completely sure weather it would be added onto the end of the current time in this case or it would just be the new purchase of it over writting the old amount of time remaining.
Yes, you can add more time; it will just push back the subscription end date. I bought another year when Amazon had a sale. Game expiration dates might not update untill you update them manually in some way, such as to start/cancel the download again.
