Redeeming your gift is easy!

1. Add the eligible STRIV Labs product to your cart.
2. Proceed to checkout.
3. Enter your promotion code in the Gift Cards & Promotional Codes section.
4. Apply the code before placing your order.

Your discount will appear before you complete your purchase.

Don't worry - this is usually easy to fix.

Please try the following:

• Make sure you're purchasing the correct product.
• Check that the code has been entered exactly as provided.

If the code still doesn't work:

1. Remove the product from your cart.

Unfortunately, no. Amazon only allows one promotion per order. If another coupon or discount has already been applied, your promotion code won't be accepted.

To redeem your gift, simply remove any other promotions before applying your code.

In some cases, Amazon may automatically apply a coupon or promotion that you previously clipped, which can prevent your gift code from being applied.

If your code still isn't working, please try the following:

1. Remove the product from your cart.
2. Add it back without selecting any other promotions or discounts.
