Sale for current FB members

I love FB and I don't want to come off as complaining but the notification about the gift card sale for current FB members did not state that the sale ended 12/24, or maybe I missed it. In hindsight, no sale last forever, but if I had known it was ending on 12/24 I would have redeemed it immediately. I did not redeem it immediately honestly because it was the busy holiday season and the instructions were not clear. So I figured I could leave it for after holiday. For me it's a bummer because my annual subscription is coming due in a few days so the timing was perfect. I will make sure I'm on top of the next time the annual membership goes on sale.
