Current GMG voucher?

GMG20-GNQYR-URU7M ?

I can't find a current one. I wish I had the money to pre-order Batman on the weekend when they had 25% off:(

This one was in my inbox, it's only for selected titles.

I like the part where the current voucher is listed on their website but you came here to ask.

TAREM-Y84B8-R3HHL extra 25% of enemy within. No idea how many times it will work but I got an email today and I'm not in a hurry to get it.

GMG25-J2566-L2GHZ for 25% these selected titles, including Batman: Arkham Origins and Call of Duty: Ghosts (Europe Only)!
