If you're signing up with Home Chef for the first time, you'll be able to enter your gift card code during the sign-up process to redeem it.
If you're an existing customer, you can apply your gift card by clicking 'Account' in the upper right corner and then selecting 'Redeem a Gift Card' or by clicking here.
Remember that promotions intended for first-time customers will not be eligible for redemption at the same time as gift card redemption during sign-up. You should apply the gift card after purchase. However, you will need to add payment information if a gift card is not applied or does not cover the full first box. Contact support for further help if needed.
