Active Junky is a good first stop before you shop any further. Sign up (free), click through its portal to over 100 online retailers—including several listed below, such as REI, EMS and Backcountry.com—and get automatic cash back on your purchases. (Every retailer has a different cash-back rate, prominently advertised.) You can also use Active Junky as a version of Google Shopping curated for outdoors lovers and active folk: search for the exact product you’re looking for and see what it sells for at Active Junky’s partners. The cash rebate is helpfully listed next to the price. Active Junky also collects coupon codes, so there’s no need to scour multiple sites to maximize your savings.
