Can I combine my Loyalty Points with another sale or coupon codes at checkout?

Only one coupon or promotion code can be used per order. You can use either your Loyalty Points or a sale coupon code, but not both at the same time. One will override the other. 

If you have redeemed your points and you see the points deducted from your account, you can find the code generated for the points you redeemed under the Rewards History section of your account.
