Bethesda - Countdown to Fallout 4 Giveaway - 11/9/15
"We're giving away Fallout gear every week until Fallout 4 comes out on November 10th.
Sign up for email newsletters from the Bethesda Store and enter to win!"
It's hard for me to tell from the rules if one entry gets you entered for all weeks or if you need to renter each period. I'll edit if anyone reads this clearer than I did.
Rules in the link and I attached the prize list image. Loads of prizes including the sold out Fallout 4 Pip Boy Edition.
