The PBS store announced today it would be offering a 20% discount on all their Ken Burns paraphernalia, in preparation of the new National Parks series that’s just around the corner.

The storefront is accepting pre-orders for the new doc series, which will be released on DVD and Blu-Ray on October 6th. For your completists out there, there are also a National Parks-themed hardcover book and audio CD, as well as jigsaw puzzles, and – oddly – Scrabble and UNO sets.

There’s free shipping for orders over $75, too. You’ll just have to wait a bit longer for the sets to arrive.
