Bethesda's online store today kicked off a week-long, Fallout-themed sale dubbed the Great War Sale Event. Along with discounts, new Fallout-branded merchandise will be introduced throughout the week, including a nice-looking Xbox One controller.

Many of the items on the store are 20 percent off (including non-Fallout items, like Quake and Wolfenstein t-shirts), with the exception of things like games and pre-sale items. You can also order the Fallout Anthology and get free shipping during the event.

Available for this week only is a Great War 2015 t-shirt. The $16 item can be ordered on its own from now until October 26 at 11:30 AM PST, or you can preorder Fallout 4 and receive it for free.

The shirt counts as the new item for Monday. Tuesday brings with it a limited-edition wired Vault-Boy Xbox One controller. Only 5,000 of these will be available, so you may need to act quickly if you want to get your hands on one.

The rest of the week will see the release of a Pip-Boy messenger bag (Wednesday), Vault-Tec watch (Thursday; 1,500 available), and a limited-edition version of the Fallout 4 art book (Friday; 5,000 available). You can see all of these in the gallery above.

This promotion comes just a few weeks ahead of the release of Fallout 4, which debuts on November 10 for Xbox One, PS4, and PC.
