My points are missing and I can't find the discount code.
Once you redeem your reward, you will be presented with your discount code. If you ever need to check back on the rewards you have redeemed, you will need to sign into your account. Then, scroll down and you will see the Rewards widget. At the bottom of it, you will see a heading that says 'Your Rewards'. Here, you will see your redeemed rewards and you can click 'view reward' beside it to bring up the discount code.
