Sierra Trading Post is celebrating their 25th anniversary, and it’s quite a party. Additional markdowns abound, plus they’re running some fabulous sweepstakes you can enter to win prizes.

If you’ve never shopped STP before (why not?), they have everything from underwear to binoculars, from pretty dresses to snowboard helmets. It’s weird, but it works.

Right now you can use coupon code AEM11 for free shipping on any order, too—even oversize items. I’m afraid my own anniversary wasn’t nearly this exciting (sorry, honey).
