I assume you have to purchase them in the same transaction as the saver fare purchase but can't confirm that.
I specifically did not want to buy the PC seats at the time of booking because it would have been all in the same transaction as the original purchase, and most likely would not have counted. However, after purchase, I went back in and went to "change seats" and did have the ability to purchase the PC seats as a separate transaction. I'm only going to do it if they are reimbursed, I'm not going to spend the money out of pocket for them. It's the "not for upgrade" language that is confusing me.
