You'll find coupons at the following site but they are very specific https://www.dealsplus.com/sierratradingpost-coupons. For instance, you might find a coupon for 20% off if you spend $75 or 25% off for hiking shoes. You'll need to look through the list to find one that you can use. There may be other sites but this is the only one I'm aware of. I don't know about express delivery but once you get to the checkout part, you'll see the options for delivery.
