We get it - hunting requires a lot of gear. That’s why we want our members to get the best gear for the best deal possible! Our rewards program issues reward points (think store credit) on all eligible purchases. Points can be redeemed on a future purchase and apply to anything in our store*.
In our rewards program, one point equals one dollar. Points are earned based on margin so it varies by product. Underneath each item in the store, you can see how many points you'll earn for purchasing that item. Anyone can shop in our gear shop, but only members can earn and redeem points!
Using your points is simple! Just log into your account and available points can be applied at checkout.
* Rewards cannot be applied to the purchase of gift certificates or gift cards.
